c05c403b1d staging: wfx: fix wrong error message
The driver checks that the number of retries made by the device is
coherent with the rate policy. However, this check make sense only if
the device has returned RETRY_EXCEEDED.

2e12ab7f05 staging: wfx: ensure that retry policy always fallbacks to MCS0 / 1Mbps
When not using HT mode, minstrel always includes 1Mbps as fallback rate.
But, when using HT mode, this fallback is not included. Yet, it seems
that it could save some frames. So, this patch add it unconditionally.

cefc203362 staging: wfx: fix rate control handling
A tx_retry_policy (the equivalent of a list of ieee80211_tx_rate in
hardware API) is not able to include a rate multiple time. So currently,
the driver merges the identical rates from the policy provided by
minstrel (and it try to do the best choice it can in the associated
flags) before to sent it to firmware.

Until now, when rates are merged, field "count" is set to
max(count1, count2). But, it means that the sum of retries for all rates
could be far less than initial number of retries. So, this patch changes
the value of field "count" to count1 + count2. Thus, sum of all retries
for all rates stay the same.

89606bb3a9 staging: wfx: fix case of lack of tx_retry_policies
In some rare cases, driver may not have any available tx_retry_policies.
In this case, the driver asks to mac80211 to stop sending data. However,
it seems that a race is possible and a few frames can be sent to the
driver. In this case, driver can't wait for free tx_retry_policies since
wfx_tx() must be atomic. So, this patch fix this case by sending these
frames with the special policy number 15.

The firmware normally use policy 15 to send internal frames (PS-poll,
beacons, etc...). So, it is not a so bad fallback.

b0ac999ebe staging: wfx: fix the cache of rate policies on interface reset
Device and driver maintain a cache of rate policies (aka.
tx_retry_policy in hardware API).

When hif_reset() is sent to hardware, device resets its cache of rate
policies. In order to keep driver in sync, it is necessary to do the
same on driver.

Note, when driver tries to use a rate policy that has not been defined
on device, data is sent at 1Mbps. So, this patch should fix abnormal
throughput observed sometime after a reset of the interface.

ab42b48f32 staging: comedi: gsc_hpdi: check dma_alloc_coherent() return value
The "auto-attach" handler function `gsc_hpdi_auto_attach()` calls
`dma_alloc_coherent()` in a loop to allocate some DMA data buffers, and
also calls it to allocate a buffer for a DMA descriptor chain.  However,
it does not check the return value of any of these calls.  Change
`gsc_hpdi_auto_attach()` to return `-ENOMEM` if any of these
`dma_alloc_coherent()` calls fail.  This will result in the comedi core
calling the "detach" handler `gsc_hpdi_detach()` as part of the
clean-up, which will call `gsc_hpdi_free_dma()` to free any allocated
DMA coherent memory buffers.

4bcd9eae73 fbtft: Fix the initialization from property algorithm
When converting to device property API the commit
8b2d3aeeb7 ("fbtft: Make use of device property API")
mistakenly placed the reading of the first value inside the loop,
that jumps over value after initialization sequence or sleep commands.

Move the above mentioned reading outside of the loop to restore
correct behaviour.

Besides that, we are using pre-increment operation which may lead to
out of the boundary access at the end of sequence. Thus, allocate buffer
with an additional element at the end to prevent out of the boundary
access.

drivers/staging/octeon/ethernet-tx.c:649:50: error:
	passing argument 1 of 'cvmx_wqe_get_grp' from incompatible pointer type

This is due to mixing, for example, cvmx_wqe_t with 'struct cvmx_wqe'.

Unfortunately, one can not just revert the primary offending commit, as doing so
results in secondary errors. This is made worse by the fact that the "removed"
typedefs still exist and are used widely outside the staging directory,
making the entire set of "remove typedef" changes pointless and wrong.

Reflect reality and mark the driver as BROKEN.

0da522107e compat_ioctl: remove most of fs/compat_ioctl.c
As part of the cleanup of some remaining y2038 issues, I came to
 fs/compat_ioctl.c, which still has a couple of commands that need support
 for time64_t.
 
 In completely unrelated work, I spent time on cleaning up parts of this
 file in the past, moving things out into drivers instead.
 
 After Al Viro reviewed an earlier version of this series and did a lot
 more of that cleanup, I decided to try to completely eliminate the rest
 of it and move it all into drivers.
 
 This series incorporates some of Al's work and many patches of my own,
 but in the end stops short of actually removing the last part, which is
 the scsi ioctl handlers. I have patches for those as well, but they need
 more testing or possibly a rewrite.

3f1b210a7f sound updates for 5.5-rc1
There have been some significant changes in the core side, both for
 ALSA and ASoC, while lots of development have been seen in SOF, as
 well as many small fixes/improvements for ASoC codecs and platforms.
 Below is a highlight in this cycle:
 
 Core:
 - The unification of PCM vmalloc buffer allocation helpers into the
   standard API
 - Clean up of the default PCM mmap handling for vmalloc & SG-buffer
 - Fix potential races at ALSA timer open
 - A few new PCM API extensions; just preliminary core changes, the
   actual changes in drivers will be merged in 5.6
 - Continued ASoC componentization works; now almost everything is a
   common ASoC component object.  A lot of refactoring and
   simplification have been done along with it.
 
 ASoC:
 - Many fixes to the Sound Open Firmware (SOF) code
 - Wake on voice support for Chromebooks
 - SPI support and trigger word detection for RT5677
 - New drivers for Analog Devices ADAU7118, Intel Cannonlake systems
   with RT1011 and RT5682, Texas Instruments TAS2562 and TAS2770
 
 HD-audio:
 - Improved Intel DSP configuration / probe code for SOF
 - Plumbing the legacy HD-audio driver with Intel SOF HDMI
 - DP-MST support for Nvidia HDMI codecs
 - Realtek quirks cleanups and new additions as usual
 
 Others:
 - Lots of refactoring and cleanups for FireWire; period-size sharing,
   h/w IRQ interval configuration, clock recovery improvements, etc
 - USB-audio: Scarlett mixer quirks
 - Cleanups of PCM calls in various drivers (including media and USB)

Merge tag 'sound-5.5-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound

Pull sound updates from Takashi Iwai:
 "There have been some significant changes in the core side, both for
  ALSA and ASoC, while lots of development have been seen in SOF, as
  well as many small fixes/improvements for ASoC codecs and platforms.
  Below is a highlight in this cycle:

  Core:
   - The unification of PCM vmalloc buffer allocation helpers into the
     standard API
   - Clean up of the default PCM mmap handling for vmalloc & SG-buffer
   - Fix potential races at ALSA timer open
   - A few new PCM API extensions; just preliminary core changes, the
     actual changes in drivers will be merged in 5.6
   - Continued ASoC componentization works; now almost everything is a
     common ASoC component object. A lot of refactoring and
     simplification have been done along with it.

  ASoC:
   - Many fixes to the Sound Open Firmware (SOF) code
   - Wake on voice support for Chromebooks
   - SPI support and trigger word detection for RT5677
   - New drivers for Analog Devices ADAU7118, Intel Cannonlake systems
     with RT1011 and RT5682, Texas Instruments TAS2562 and TAS2770

  HD-audio:
   - Improved Intel DSP configuration / probe code for SOF
   - Plumbing the legacy HD-audio driver with Intel SOF HDMI
   - DP-MST support for Nvidia HDMI codecs
   - Realtek quirks cleanups and new additions as usual

  Others:
   - Lots of refactoring and cleanups for FireWire; period-size sharing,
     h/w IRQ interval configuration, clock recovery improvements, etc
   - USB-audio: Scarlett mixer quirks
   - Cleanups of PCM calls in various drivers (including media and USB)
     to adapt the core API changes"

0f6f874987 staging: vchiq: Have vchiq_dump_* functions return an error code
These functions currently modify the struct dump_context passed
to them, and set context->actual to -EFAULT in case of error.
The issue is that this is never returned to the user (except
accidentally when things align so that that happens). So, have
these functions return 0 on success and the appropriate error
code otherwise, and return nonzero errors to the user.

Remove a coding style error from the Octeon driver's tree and keep
checkpatch.pl a little quieter.

Being a white-spaces patch the chances of breakage are minimal; we don't
have the hardware to run this driver so we built it with COMPILE_TEST
enabled on an x86 machine.

5618332e5b staging: comedi: usbduxfast: usbduxfast_ai_cmdtest rounding error
The userspace comedilib function 'get_cmd_generic_timed' fills
the cmd structure with an informed guess and then calls the
function 'usbduxfast_ai_cmdtest' in this driver repeatedly while
'usbduxfast_ai_cmdtest' is modifying the cmd struct until it
no longer changes. However, because of rounding errors this never
converged because 'steps = (cmd->convert_arg * 30) / 1000' and then
back to 'cmd->convert_arg = (steps * 1000) / 30' won't be the same
because of rounding errors. 'Steps' should only be converted back to
the 'convert_arg' if 'steps' has actually been modified. In addition
the case of steps being 0 wasn't checked which is also now done.
