staging: rtl8712: Drop get_recvframe_data()

As done for rtl8723bs and r8188eu, drop get_recvframe_data(), as it
introduces an impossible value (NULL) for the compiler to check code
paths against which could result in nonsensical warnings.

Since the WF200 VID/PID are not reliable, it's recommended to declare it
in the DT. Until now, if the device was not declared, the driver just
printed a warning and continue. But, the risk of a collision is too

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.

Merge tag 'trace-v5.17-3' of git://git./linux/kernel/git/rostedt/linux-trace

Pull ftrace fix from Steven Rostedt:
 "Fix s390 breakage from sorting mcount tables.

  The latest merge of the tracing tree sorts the mcount table at build
  time. But s390 appears to do things differently (like always) and
  replaces the sorted table back to the original unsorted one. As the
  ftrace algorithm depends on it being sorted, bad things happen when it
  is not, and s390 experienced those bad things.

  Add a new config to tell the boot if the mcount table is sorted or
  not, and allow s390 to opt out of it"

* tag 'trace-v5.17-3' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace:
  ftrace: Fix assuming build time sort works for s390

ftrace: Fix assuming build time sort works for s390

To speed up the boot process, as mcount_loc needs to be sorted for ftrace
to work properly, sorting it at build time is more efficient than boot up
and can save milliseconds of time. Unfortunately, this change broke s390
as it will modify the mcount_loc location after the sorting takes place
and will put back the unsorted locations. Since the sorting is skipped at
boot up if it is believed that it was sorted at run time, ftrace can crash
as its algorithms are dependent on the list being sorted.

Add a new config BUILDTIME_MCOUNT_SORT that is set when
BUILDTIME_TABLE_SORT but not if S390 is set. Use this config to determine
if sorting should take place at boot up.
