b2aa4f8069 ALSA: rme9652: Fix the missing snd_card_free() call at probe error
The previous cleanup with devres may lead to the incorrect release
orders at the probe error handling due to the devres's nature.  Until
we register the card, snd_card_free() has to be called at first for
releasing the stuff properly when the driver tries to manage and
release the stuff via card->private_free().

This patch fixes it by calling snd_card_free() manually on the error
from the probe callback.

43d35ccc36 ALSA: pci: rme: Fix unaligned buffer addresses
The recent fix for setting up the DMA buffer type on RME drivers tried
to address the non-standard memory managements and changed the DMA
buffer information to the standard snd_dma_buffer object that is
allocated at the probe time.  However, I overlooked that the RME
drivers handle the buffer addresses based on 64k alignment, and the
previous conversion broke that silently.

This patch is an attempt to fix the regression.  The snd_dma_buffer
objects are copied to the original data with the correction to the
aligned accesses, and those are passed to snd_pcm_set_runtime_buffer()
helpers instead.  The original snd_dma_buffer objects are managed by
devres, hence they'll be released automagically.

0899a7a230 ALSA: pci: rme: Set up buffer type properly
Although the regression of the mmap was fixed in the recent commit
dc0dc8a73e ("ALSA: pcm: Fix mmap breakage without explicit buffer
setup"), RME9652 and HDSP drivers have still potential issues with
their mmap handling.  Namely, they use the default mmap handler
without the standard buffer preallocation, and PCM core wouldn't use
the coherent DMA mapping.  It's practically OK on x86, but on some
exotic architectures, it wouldn't work.

This patch addresses the potential breakage by replacing the buffer
setup with the proper macro.  It also simplifies the source code,
too.

b1002b2d41 ALSA: rme9652: Allocate resources with device-managed APIs
This patch converts the resource management in PCI rme9652 driver with
devres as a clean up.  Each manual resource management is converted
with the corresponding devres helper, the page allocations are done
with the devres helper, and the card object release is managed now via
card->private_free instead of a lowlevel snd_device.

This should give no user-visible functional changes.

9ebb3697c8 ALSA: rme9652: Fix assignment in if condition
PCI RME9652 driver code contains lots of assignments in if condition,

5b1ed7df01 ALSA: control - add generic LED API
This patchset tries to resolve the diversity in the audio LED
 control among the ALSA drivers. A new control layer registration
 is introduced which allows to run additional operations on
 top of the elementary ALSA sound controls.
 
 A new control access group (three bits in the access flags)
 was introduced to carry the LED group information for
 the sound controls. The low-level sound drivers can just
 mark those controls using this access group. This information
 is not exported to the user space, but user space can
 manage the LED sound control associations through sysfs
 (last patch) per Mark's request. It makes things fully
 configurable in the kernel and user space (UCM).
 
 The actual state ('route') evaluation is really easy
 (the minimal value check for all channels / controls / cards).
 If there's more complicated logic for a given hardware,
 the card driver may eventually export a new read-only
 sound control for the LED group and do the logic itself.
 
 The new LED trigger control code is completely separated
 and possibly optional (there's no symbol dependency).
 The full code separation allows eventually to move this
 LED trigger control to the user space in future.
 Actually it replaces the already present functionality
 in the kernel space (HDA drivers) and allows a quick adoption
 for the recent hardware (ASoC codecs including SoundWire).

 1) call snd_ctl_led_request() when control LED layer should be

 2) mark all related kcontrols with

fb95aae6e6 sound updates for 5.6-rc1
As diffstat shows we've had again a lot of works done for this cycle:
 majority of changes are the continued componentization and code
 refactoring in ASoC, the tree-wide PCM API updates and cleanups
 and SOF updates while a few ASoC driver updates are seen, too.
 
 Here we go, some highlights:
 
 Core:
 - Finally y2038 support landed to ALSA ABI;
   some ioctls have been extended and lots of tricks were applied
 - Applying the new managed PCM buffer API to all drivers;
   the API itself was already merged in 5.5
 - The already deprecated dimension support in ALSA control API is
   dropped completely now
 - Verification of ALSA control elements to catch API misuses
 
 ASoC:
 - Further code refactorings and moving things to the component level
 - Lots of updates and improvements on SOF / Intel drivers;
   now including common HDMI driver and SoundWire support
 - New driver support for Ingenic JZ4770, Mediatek MT6660, Qualcomm
   WCD934x and WSA881x, and Realtek RT700, RT711, RT715, RT1011, RT1015
   and RT1308
 
 HD-audio:
 - Improved ring-buffer communications using waitqueue
 - Drop the superfluous buffer preallocation on x86
 
 Others:
 - Many code cleanups, mostly constifications over the whole tree
 - USB-audio: quirks for MOTU, Corsair Virtuoso, Line6 Helix
 - FireWire: code refactoring for oxfw and dice drivers

6769e988b0 ALSA: constify snd_pcm_ops structures
Check for snd_pcm_ops structures that are only stored in the ops field of a
snd_soc_platform_driver structure or passed as the third argument to
snd_pcm_set_ops.  The corresponding field or parameter is declared const,
so snd_pcm_ops structures that have this property can be declared as const
also.

The semantic patch that makes this change is as follows:

47d98c026e ALSA: Remove memory reservation code from memalloc helper
Nowadays we have CMA for obtaining the contiguous memory pages
efficiently.  Let's kill the old kludge for reserving the memory pages
for large buffers.  It was rarely useful (only for preserving pages
among module reloading or a little help by an early boot scripting),
used only by a couple of drivers, and yet it gives too much ugliness

As drvdata is cleared to NULL at probe failure or at removal by the
driver core, we don't have to call pci_set_drvdata(pci, NULL) any
longer in each driver.

The only remaining pci_set_drvdata(NULL) is in azx_firmware_cb() in
hda_intel.c.  Since this function itself releases the card instance,
we need to clear drvdata here as well, so that it won't be released
doubly in the remove callback.

The convention for pci_driver.name entry in kernel drivers seem to be
the module name or equivalent ones.  But, so far, almost all PCI sound
drivers use more verbose name like "ABC Xyz (12)", and these are fairly
confusing when appearing as a file name.

This patch converts the all pci_driver.name entries in sound/pci/* to
use KBUILD_MODNAME for more unified appearance.

5a0e3ad6af include cleanup: Update gfp.h and slab.h includes to prepare for breaking implicit slab.h inclusion from percpu.h
percpu.h is included by sched.h and module.h and thus ends up being
included when building most .c files.  percpu.h includes slab.h which
in turn includes gfp.h making everything defined by the two files
universally available and complicating inclusion dependencies.

percpu.h -> slab.h dependency is about to be removed.  Prepare for
this change by updating users of gfp and slab facilities include those
headers directly instead of assuming availability.  As this conversion
needs to touch large number of source files, the following script is
used as the basis of conversion.

  http://userweb.kernel.org/~tj/misc/slabh-sweep.py

The script does the followings.

* Scan files for gfp and slab usages and update includes such that
  only the necessary includes are there.  ie. if only gfp is used,
  gfp.h, if slab is used, slab.h.

* When the script inserts a new include, it looks at the include
  blocks and try to put the new include such that its order conforms
  to its surrounding.  It's put in the include block which contains
  core kernel includes, in the same order that the rest are ordered -
  alphabetical, Christmas tree, rev-Xmas-tree or at the end if there
  doesn't seem to be any matching order.

* If the script can't find a place to put a new include (mostly
  because the file doesn't have fitting include block), it prints out
  an error message indicating which .h file needs to be added to the
  file.

The conversion was done in the following steps.

1. The initial automatic conversion of all .c files updated slightly
   over 4000 files, deleting around 700 includes and adding ~480 gfp.h
   and ~3000 slab.h inclusions.  The script emitted errors for ~400
   files.

2. Each error was manually checked.  Some didn't need the inclusion,
   some needed manual addition while adding it to implementation .h or
   embedding .c file was more appropriate for others.  This step added
   inclusions to around 150 files.

3. The script was run again and the output was compared to the edits
   from #2 to make sure no file was left behind.

4. Several build tests were done and a couple of problems were fixed.
   e.g. lib/decompress_*.c used malloc/free() wrappers around slab
   APIs requiring slab.h to be added manually.

5. The script was run on all .h files but without automatically
   editing them as sprinkling gfp.h and slab.h inclusions around .h
   files could easily lead to inclusion dependency hell.  Most gfp.h
   inclusion directives were ignored as stuff from gfp.h was usually
   wildly available and often used in preprocessor macros.  Each
   slab.h inclusion directive was examined and added manually as
   necessary.

6. percpu.h was updated not to include slab.h.

7. Build test were done on the following configurations and failures
   were fixed.  CONFIG_GCOV_KERNEL was turned off for all tests (as my
   distributed build env didn't work with gcov compiles) and a few
   more options had to be turned off depending on archs to make things
   build (like ipr on powerpc/64 which failed due to missing writeq).

   * x86 and x86_64 UP and SMP allmodconfig and a custom test config.
   * powerpc and powerpc64 SMP allmodconfig
   * sparc and sparc64 SMP allmodconfig
   * ia64 SMP allmodconfig
   * s390 SMP allmodconfig
   * alpha SMP allmodconfig
   * um on x86_64 SMP allmodconfig

8. percpu.h modifications were reverted so that it could be applied as
   a separate patch and serve as bisection point.

Given the fact that I had only a couple of failures from tests on step
6, I'm fairly confident about the coverage of this conversion patch.
If there is a breakage, it's likely to be something in one of the arch
headers which should be easily discoverable easily on most builds of
the specific arch.
