Re: [PATCH wireless] wifi: mt76: mt792x: fix NULL dereference in ACPI SAR init during probe

[Devin Wittmayer]

Thorsten,

Thanks for pointing Linus at it, that's pretty cool.

There's nothing to set straight as far as I could find so no additional
patches to send. I went through it pretty thoroughly against mainline
this afternoon.

No stable backport needed. Both commits it fixes first appear in
v7.3-rc1, so the regression never reached a release.

Felix's tree carries no competing fix and has not touched that file
since October from what I could find.

The two patches still queued for that file, Junjie's 0xff one and my
table-layout one, both apply cleanly on top, so nothing got stranded.

Thanks again,

Devin
