Regression report for mainline, extra issue [2022-03-18]

[Thorsten Leemhuis <regressions@leemhuis.info>]

Hi Linus! Just FYI, a couple of regression reports showed up in the
last few days and I thought you might wanted to known about them
a bit before releasing 5.17. Hence a quick manual regression
report focusing on regression from this cycle:


[ *NEW* ] HID: multitouch: right touchpad button is disabled on recent kernels

Patch is available and was tested successfully today, but looks
like José only wants to sent it out for review next week:

There are two patches to fix this, Steve might sent one to you
soon:

Introduced in v5.16..v5.17-rc5

This was known for a while, but regzbot didn't sort it properly
into the "regressions from this cycle" category. Sorry about that.
Anyway:

No fix in sight (devs tried in the past few days) and reporter
has no way to test patches in the next few days:

[ *NEW* ] "vmwgfx: probe of 0000:00:0f.0 failed with error -16" in guest

According to the bugzilla ticket it seems to be a regression from
this cycle. A fix is available here (included in -next since early
February :-/ ):
https://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git/commit/?id=27599aacbaefcbf2af7b06b0029459bbf682000d

But according to the patch description its fixing a issue introduced
in 5.11. Not sure who's right.


MISC
----
FWIW, I just noticed there is a new regression report in bko
which I didn't look closer at yet; looks like it's a report
from a distro (Fedora) kernel, but I'd thought I nevertheless
briefly mention it:

Bug 215696 - Kernel Oops since kernel-5.17 on dual socket Intel
Xeon Gold servers - kernel NULL pointer dereference 
https://bugzilla.kernel.org/show_bug.cgi?id=215696

Ciao, Thorsten
