dfdc1de642 Merge tag 'staging-5.18-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging 
Pull staging driver updates from Greg KH:
 "Here is the big set of staging driver updates for 5.18-rc1.

  Loads of tiny cleanups for almost all staging drivers in here, nothing
  major at all. Highlights include:

   - remove the ashmem Android driver. It is long-dead and if there are
     any legacy userspace applications still using it, the Android
     kernel images will maintain it, the community shouldn't care about
     it anymore

   - wfx wifi driver major cleanups. Should be ready to merge out of
     staging soon, and will coordinate with the wifi maintainers after
     -rc1 is out

   - major cleanups and unwinding of the layers of the r8188eu driver.
     It's amazing just how many unneeded layers of abstraction is in
     there, just when we think it's done, another is found...

   - lots of tiny coding style cleanups in many other staging drivers.

  All have been in linux-next for a while with no reported problems"

c86176d513 staging: wfx: ensure HIF request has been sent before polling 
wfx_bh_request_tx() send HIF request asynchronously through bh_work().
Then the caller will run wfx_bh_poll_irq() to poll the answer.

However it useless to burn CPU cycles for the polling while the request
has yet been sent. Worse, wfx_bh_poll_irq() may get the CPU and prevent
wfx_bh_request_tx() to run. This problem has been observed on mono core
architecture.

This first exchange is correct:

Some variants of the WF200 disallow active scan on channel 12 and 13.
For these parts, the channels 12 and 13 are marked IEEE80211_CHAN_NO_IR.

However, the beacon hint procedure was removing the flag
IEEE80211_CHAN_NO_IR from channels where a BSS is discovered. This was
making subsequent scans to fail because the driver was trying active
scans on prohibited channels.

Until now, the SDIO quirks are applied directly from the driver.
However, it is better to apply the quirks before driver probing. So,
this patch relocate the quirks in the MMC framework.

Note that the WF200 has no valid SDIO VID/PID. Therefore, we match DT
rather than on the SDIO VID/PID.

Until now, the driver had to parse the PDS file before to send it. This

changed the PDS format so it is now an array of Type-Length-Value.

This patch allows to support new format and keep compatibility with

a0386bba70 spi: make remove callback a void function 
The value returned by an spi driver's remove function is mostly ignored.
(Only an error message is printed if the value is non-zero that the
error is ignored.)

So change the prototype of the remove function to return no value. This
way driver authors are not tempted to assume that passing an error to
the upper layer is a good idea. All drivers are adapted accordingly.
There is no intended change of behaviour, all callbacks were prepared to
return 0 before.

1ad0104e94 staging: wfx: map 'compatible' attribute with board name 
"WF200" only designates the chip. To make a WiFi board, the chip must be
associated with an antenna. The antenna configuration is located in
separate files (aka PDS files in Silabs wording). Currently, user has to
write in his DT something like:

    compatible = "silabs,wf200";
    config = "brd4001a.pds";

It is far better to embed a list of known boards (chip + antenna) in the
driver. So the user just have to declare:

    compatible = "silabs,brd4001a";

This patch add the configurations for the evaluation boards sold by
Silabs. To provide a full plug-and-play experience, the associated PDS
files[1] will be available in linux-firmware.

This patch does not break compatibility with existing setups.

f545b23d47 staging: wfx: reformat comments on 100 columns 
Until now, this driver was written in 80 columns style. However, since
all the functions are prefixed with "wfx_", this constraint is no more
respected in the last patches.

From the perspective of kernel Coding Style, it is not a problem since
it is now allowed to write code on 100 columns.

This patch just unify the code to use 100 columns in every comments.

declare it with little endian fields.

It is now a bit more verbose to access to fields of struct
hif_ind_startup, but it is less confusing.
