f996c49d4f usb-misc: sisusbvga: Fix coding style: braces, parenthesis, comment
The file drivers/usb/misc/sisusbvga/sisusb.c contained coding style
issues reported by checkpatch. This patch fixes the following
errors:
 - 12 WARNING: braces {} are not necessary for single statement blocks
 - 04 ERROR: return is not a function, parentheses are not required
 - 03 ERROR: do not initialise statics to 0
 - 1 WARNING: else is not generally useful after a break or return
 - 1 WARNING: braces {} are not necessary for any arm of this statement
 - 1 WARNING: Block comments use * on subsequent lines

One case in which braces are not necessary is left unchanged as other
patch of the series will fix it.

06e21efa2d usb-misc: sisusbvga: Fix coding style: vertical whitespace changes
This patch fixes whitespace coding style issues that can't be fixed
without adding newlines. This patch fixes the following checkpatch
warnings:
 - 20 ERROR: trailing statements should be on next line
 - 15 WARNING: line over 80 characters
 - 03 WARNING: Missing a blank line after declarations
 - 01 ERROR: space required after that ','

Five lines over 80 characters are left. The first three wont change as
the fix would require split the cast and variable name in different
lines which makes the code less readable. The last two will be fixed by
other patch in the series.

e3e2e36c10 ehci-hcd: Disable memory-write-invalidate when the driver is removed
The driver calls pci_set_mwi to enable memory-write-invalidate when it
is initialized, but does not call pci_clear_mwi when it is removed. Many
other drivers calls pci_clear_mwi when pci_set_mwi is called, such as
r8169, 8139cp and e1000.

This patch adds a function "ehci_pci_remove" to remove the pci driver.
This function calls pci_clear_mwi and usb_hcd_pci_remove, which can
fix the problem.

e8f55b9148 usb: host: ehci-msm: Fix register initialization
The default value for the 'transceiver select' field of
the PORTSC register may not always be correct. Previously
the phy-msm-usb driver would do this for us, but since
ehci-msm can now be instantiated standalone without any PHY
driver, the register needs to be explicitly initialized to
ULPI mode to properly communicate with the PHY.

This is not readily apparent, as firmware or bootloader code
also happen to pre-initialize this for us. However, it can
manifest when performing a driver unbind/rebind as follows:

 cd /sys/bus/platform/drivers/msm_hsusb_host
 echo QCOM8040:00 > unbind
 echo QCOM8040:00 > bind

The EHCI core executes a controller reset as part of this,
and as a result the register in question would revert to
its default state and must be re-initialized properly.
Furthermore this may be useful in the future when adding
PM suspend/resume support.

c4398ef609 usb: host: ehci-msm: Remove dependency on OTG PHY
Currently the EHCI MSM driver has a hard dependency to be created
by an OTG layer, namely the phy-msm-usb driver. In some cases or
board configurations we want to allow the EHCI host to be
instantiated without OTG capability. Instead, relax the dependency
on having an OTG PHY being present and call usb_add_hcd() directly.

adbff3a4f9 USB: bcma: separate code initializing USB 2.0 core
This splits one big probing function into two smaller ones. The main one
is now responsible for the generic stuff: allocating memory & enabling
power using GPIO. The new one contains code that is specific to the USB
2.0 bcma core.
This will allow adding support for the USB 3.0 bcma core (handling XHCI)
in the future.

352d9e2ee8 USB: bcma: make helper creating platform dev more generic
Having "bool ohci" argument in bcma_hcd_create_pdev function limited it
to support two cases only (OHCI and EHCI) and put too much logic in it.
Lets make caller pass all required data. This adds few extra arguments
to the function call but will allow us to reuse this code and handle
more cases in the future (e.g. add XHCI support).

f8868ed007 usb: core: use kbasename() instead of open-coded variant
kbasename() helper is dedicated to find a last part of the filename or
pathname. USB core uses open-coded variant of that helper.

Replace some lines of code by kbasename() call.

The current users do not have trailing slash and we are on the safe side to
make such change. I dig a history of the code under question up and found the
patch [1] that brought it along with the same to tty layer. The check for
trailing slash looks like copy'n'paste thing and I consider it as redundant.

0cdd49a1d1 usb: Support USB 3.1 extended port status request
usb 3.1 extend the hub get-port-status request by adding different
request types. the new request types return 4 additional bytes called
extended port status, these bytes are returned after the regular
portstatus and portchange values.

The extended port status contains a speed ID for the currently used
sublink speed. A table of supported Speed IDs with details about the link
is provided by the hub in the device descriptor BOS SuperSpeedPlus
device capability Sublink Speed Attributes.

Support this new request. Ask for the extended port status after port
reset if hub supports USB 3.1. If link is running at SuperSpeedPlus
set the device speed to USB_SPEED_SUPER_PLUS

6b31de3e69 ideapad-laptop: Add Lenovo Yoga 700 to no_hw_rfkill dmi list
Like the Yoga 900 models the Lenovo Yoga 700 does not have a
hw rfkill switch, and trying to read the hw rfkill switch through the
ideapad module causes it to always reported blocking breaking wifi.

This commit adds the Lenovo Yoga 700 to the no_hw_rfkill dmi list, fixing
the wifi breakage.

587198ba52 vmstat: Remove BUG_ON from vmstat_update
If we detect that there is nothing to do just set the flag and do not
check if it was already set before.  Races really do not matter.  If the
flag is set by any code then the shepherd will start dealing with the
situation and reenable the vmstat workers when necessary again.

Since commit 0eb77e9880 ("vmstat: make vmstat_updater deferrable again
and shut down on idle") quiet_vmstat might update cpu_stat_off and mark
a particular cpu to be handled by vmstat_shepherd.  This might trigger a
VM_BUG_ON in vmstat_update because the work item might have been
sleeping during the idle period and see the cpu_stat_off updated after
the wake up.  The VM_BUG_ON is therefore misleading and no more
appropriate.  Moreover it doesn't really suite any protection from real
bugs because vmstat_shepherd will simply reschedule the vmstat_work
anytime it sees a particular cpu set or vmstat_update would do the same
from the worker context directly.  Even when the two would race the
result wouldn't be incorrect as the counters update is fully idempotent.

25f66096ac MIPS: zboot: Avoid useless rebuilds
Add dummy.o to the targets list, and fill targets automatically from
$(vmlinuzobjs) to avoid having to maintain two lists.

When building with XZ compression copy ashldi3.c to the build
directory to use a different object file for the kernel and zboot.
Without this the same object file need to be build with different
flags which cause a rebuild at every run.
