ath12k firmware regression with update 82318c966fd1

[Takashi Iwai]

Hi,

it seems that the recent update of ath12k WCN7850 board-2.bin update
broke WiFi on Lenovo Thinkpad 14 Gen 5 AMD.  Reverting to the older
firmware seems fixing the issue.

The report for openSUSE Tumbleweed is found at
  https://bugzilla.suse.com/show_bug.cgi?id=1230596
and for Arch
  https://bbs.archlinux.org/viewtopic.php?id=299286

Let me know if it's already handled in Qualcomm and the fix is
expected shortly.  Otherwise I'll try to revert the change locally for
TW as a temporary solution.


thanks,

Takashi

Just to clarify, reverting to an older board-2.bin seems to fix the
issue. (Board files are basically calibration data)

For easier tracking can someone file a bug to bugzilla.kernel.org? Also
please include more information:

This is the first time I'm hearing about this and to my knowledge there
is not fix pending.
