c2a96b7f18 Driver core changes for 6.11-rc1
Here is the big set of driver core changes for 6.11-rc1.
 
 Lots of stuff in here, with not a huge diffstat, but apis are evolving
 which required lots of files to be touched.  Highlights of the changes
 in here are:
   - platform remove callback api final fixups (Uwe took many releases to
     get here, finally!)
   - Rust bindings for basic firmware apis and initial driver-core
     interactions.  It's not all that useful for a "write a whole driver
     in rust" type of thing, but the firmware bindings do help out the
     phy rust drivers, and the driver core bindings give a solid base on
     which others can start their work.  There is still a long way to go
     here before we have a multitude of rust drivers being added, but
     it's a great first step.
   - driver core const api changes.  This reached across all bus types,
     and there are some fix-ups for some not-common bus types that
     linux-next and 0-day testing shook out.  This work is being done to
     help make the rust bindings more safe, as well as the C code, moving
     toward the end-goal of allowing us to put driver structures into
     read-only memory.  We aren't there yet, but are getting closer.
   - minor devres cleanups and fixes found by code inspection
   - arch_topology minor changes
   - other minor driver core cleanups
 
 All of these have been in linux-next for a very long time with no
 reported problems.

d69d804845 driver core: have match() callback in struct bus_type take a const *
In the match() callback, the struct device_driver * should not be
changed, so change the function callback to be a const *.  This is one
step of many towards making the driver core safe to have struct
device_driver in read-only memory.

Because the match() callback is in all busses, all busses are modified
to handle this properly.  This does entail switching some container_of()
calls to container_of_const() to properly handle the constant *.

For some busses, like PCI and USB and HV, the const * is cast away in
the match callback as those busses do want to modify those structures at
this point in time (they have a local lock in the driver structure.)
That will have to be changed in the future if they wish to have their
struct device * in read-only-memory.

1b775e616e pcmcia: xxs1500_ss: Convert to platform remove callback returning void
The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is ignored (apart
from emitting a warning) and this typically results in resource leaks.

To improve here there is a quest to make the remove callback return
void. In the first step of this quest all drivers are converted to
.remove_new(), which already returns void. Eventually after all drivers
are converted, .remove_new() will be renamed to .remove().

Trivially convert this driver from always returning zero in the remove
callback to the void returning variant.

Afer commit 1fa5ae857b ("driver core: get rid of struct device's
bus_id string array"), the name of device is allocated dynamically.
Therefore, it needs to be freed, which is done by the driver core for
us once all references to the device are gone. Therefore, move the
dev_set_name() call immediately before the call device_register(), which
either succeeds (then the freeing will be done upon subsequent remvoal),
or puts the reference in the error call. Also, it is not unusual that the
return value of dev_set_name is not checked.

As the comment of device_register() says, it should use put_device()
to give up the reference in the error path. Then, insofar resources
will be freed in pcmcia_release_dev(), the error path is no longer
needed. In particular, this means that the (previously missing) dropping
of the reference to &p_dev->function_config->ref is now handled by
pcmcia_release_dev().

If device_register() returns error in pccardd(), it leads two issues:

1. The socket_released has never been completed, it will block
   pcmcia_unregister_socket(), because of waiting for completion
   of socket_released.
2. The device name allocated by dev_set_name() is leaked.

Fix this two issues by calling put_device() when device_register() fails.
socket_released can be completed in pcmcia_release_socket(), the name can
be freed in kobject_cleanup().

acdbfa0481 pcmcia : make PCMCIA depend on HAS_IOMEM
On s390 systems (aka mainframes), it has classic channel devices for
networking and permanent storage that are currently even more common
than PCI devices. Hence it could have a fully functional s390 kernel
with CONFIG_PCI=n, then the relevant iomem mapping functions
[including ioremap(), devm_ioremap(), etc.] are not available.

Here let depend PCMCIA on HAS_IOMEM so that it won't be built to
cause below compiling error if PCI is unset.

c85fd9422f pcmcia: rsrc_nonstatic: Fix memory leak in nonstatic_release_resource_db()
When nonstatic_release_resource_db() frees all resources associated

a memory leak observable with kmemleak:

2243acd50a driver core: class: remove struct class_interface * from callbacks
The add_dev and remove_dev callbacks in struct class_interface currently
pass in a pointer back to the class_interface structure that is calling
them, but none of the callback implementations actually use this pointer
as it is pointless (the structure is known, the driver passed it in in
the first place if it is really needed again.)

So clean this up and just remove the pointer from the callbacks and fix
up all callback functions.

979207cac5 driver core: class: mark class_release() as taking a const *
The struct class callback, class_release(), is only called in 2 places,
the pcmcia cardservices code, and in the class driver core code.  Both
places it is safe to mark the structure as a const *, to allow us to
in the future mark all struct class usages as constant and move into
read-only memory.

a93e884edf Driver core changes for 6.3-rc1
Here is the large set of driver core changes for 6.3-rc1.
 
 There's a lot of changes this development cycle, most of the work falls
 into two different categories:
   - fw_devlink fixes and updates.  This has gone through numerous review
     cycles and lots of review and testing by lots of different devices.
     Hopefully all should be good now, and Saravana will be keeping a
     watch for any potential regression on odd embedded systems.
   - driver core changes to work to make struct bus_type able to be moved
     into read-only memory (i.e. const)  The recent work with Rust has
     pointed out a number of areas in the driver core where we are
     passing around and working with structures that really do not have
     to be dynamic at all, and they should be able to be read-only making
     things safer overall.  This is the contuation of that work (started
     last release with kobject changes) in moving struct bus_type to be
     constant.  We didn't quite make it for this release, but the
     remaining patches will be finished up for the release after this
     one, but the groundwork has been laid for this effort.
 
 Other than that we have in here:
   - debugfs memory leak fixes in some subsystems
   - error path cleanups and fixes for some never-able-to-be-hit
     codepaths.
   - cacheinfo rework and fixes
   - Other tiny fixes, full details are in the shortlog
 
 All of these have been in linux-next for a while with no reported
 problems.

292a089d78 treewide: Convert del_timer*() to timer_shutdown*()
Due to several bugs caused by timers being re-armed after they are
shutdown and just before they are freed, a new state of timers was added
called "shutdown".  After a timer is set to this state, then it can no
longer be re-armed.

The following script was run to find all the trivial locations where
del_timer() or del_timer_sync() is called in the same function that the
object holding the timer is freed.  It also ignores any locations where
the timer->function is modified between the del_timer*() and the free(),
as that is not considered a "trivial" case.

This was created by using a coccinelle script and the following
commands:

    $ cat timer.cocci
    @@
    expression ptr, slab;
    identifier timer, rfield;
    @@
    (
    -       del_timer(&ptr->timer);
    +       timer_shutdown(&ptr->timer);
    |
    -       del_timer_sync(&ptr->timer);
    +       timer_shutdown_sync(&ptr->timer);
    )
      ... when strict
          when != ptr->timer
    (
            kfree_rcu(ptr, rfield);
    |
            kmem_cache_free(slab, ptr);
    |
            kfree(ptr);
    )

15e74c6c1c pcmcia: remove AT91RM9200 Compact Flash driver
As noted by Arnd Bergmann, "we used to have three drivers for the same
hardware (pcmcia, pata and ide), and only the pcmcia driver remained
in the tree after drivers/ide/ was removed and pata_at91 did not get
converted to DT". "There is no dts file in tree that actually declares
either of them, so chances are that nobody is actually using the CF
slot on at91 any more."[1]

On this rationale, remove the AT91RM9200 Compact Flash driver, which
also assists in reaching "the goal of stopping exporting OF-specific
APIs of gpiolib".[2]

09b2c10d62 pcmcia: sa1100: Make sa11x0_drv_pcmcia_legacy_remove() return void
sa11x0_drv_pcmcia_legacy_remove() returns zero unconditionally. Letting it
return void instead makes it easier to see in the caller that there is no
error to handle.

This is a preparation for making platform remove callbacks return void.

96479c0980 ARM: multiplatform changes, part 2
The second part of the multiplatform changes now converts the
 Intel/Marvell PXA platform along with the rest. The patches went through
 several rebases before the merge window as bugs were found, so they
 remained separate.
 
 This has to touch a lot of drivers, in particular the touchscreen,
 pcmcia, sound and clk bits, to detach the driver files from the
 platform and board specific header files.

2ef4bb24ff pcmcia: Use platform_get_irq() to get the interrupt
It is not recommened to use platform_get_resource(pdev, IORESOURCE_IRQ)
for requesting IRQ's resources any more, as they can be not ready yet in
case of DT-booting.

platform_get_irq() instead is a recommended way for getting IRQ even if
it was not retrieved earlier.

It also makes code simpler because we're getting "int" value right away
and no conversion from resource to int is required.

645b302673 ARM: pxa/sa1100: move I/O space to PCI_IOBASE
PXA and StrongARM1100 traditionally map their I/O space 1:1 into virtual
memory, using a per-bus io_offset that matches the base address of the
ioremap mapping.

In order for PXA to work in a multiplatform config, this needs to
change so I/O space starts at PCI_IOBASE (0xfee00000). Since the pcmcia
soc_common support is shared with StrongARM1100, both have to change at
the same time. The affected machines are:

 - Anything with a PCMCIA slot now uses pci_remap_iospace, which
   is made available to PCMCIA configurations as well, rather than
   just PCI. The first PCMCIA slot now starts at port number 0x10000.

 - The Zeus and Viper platforms have PC/104-style ISA buses,
   which have a static mapping for both I/O and memory space at
   0xf1000000, which can no longer work. It does not appear to have
   any in-tree users, so moving it to port number 0 makes them
   behave like a traditional PC.

 - SA1100 does support ISA slots in theory, but all machines that
   originally enabled this appear to have been removed from the tree
   ages ago, and the I/O space is never mapped anywhere.

 - The Nanoengine machine has support for PCI slots, but looks
   like this never included I/O space, the resources only define the
   location for memory and config space.

With this, the definitions of __io() and IO_SPACE_LIMIT can be simplified,
as the only remaining cases are the generic PCI_IOBASE and the custom
inb()/outb() macros on RiscPC.  S3C24xx still has a custom inb()/outb()
in this here, but this is already removed in another branch.

df99e7bbbe ARM: omap1: use pci_remap_iospace() for omap_cf
The ISA I/O space handling in omap_cf is incompatible with
PCI drivers in a multiplatform kernel, and requires a custom
mach/io.h.

Change the driver to use pci_remap_iospace() like PCI drivers do,
so the generic ioport access can work across platforms.

To actually use that code, we have to select CONFIG_PCI
here.

Move them into the same place as the actual board file to avoid

08d3df8c81 ARM: pxa: split up mach/hardware.h
The mach/hardware.h is included in lots of places, and it provides
three different things on pxa:

- the cpu_is_pxa* macros
- an indirect inclusion of mach/addr-map.h
- the __REG() and io_pv2() helper macros

Split it up into separate <linux/soc/pxa/cpu.h> and mach/pxa-regs.h
headers, then change all the files that use mach/hardware.h to
include the exact set of those three headers that they actually
need, allowing for further more targeted cleanup.

linux/soc/pxa/cpu.h can remain permanently exported and is now in
a global location along with similar headers. pxa-regs.h and
addr-map.h are only used in a very small number of drivers now
and can be moved to arch/arm/mach-pxa/ directly when those drivers
are to pass the necessary data as resources.

ARM: pxa: remove Intel Imote2 and Stargate 2 boards
I have no reason to believe these boards have any more users and I
haven't tested them for several years.  Removing them may simplify
other changes to the various PXA boards people still care about.
The recent conversion of pxa2xx_spi to GPIO descriptors for example
had to update this board despite no one caring or testing.

Great boards that got me started in kernel development, RIP!
