Subject: [Regression] Lenovo Thinkpad X1 Carbon Gen 10 first S2idle fails,
 S0ix fails in all further suspends

Hi, Thorsten here, the Linux kernel's regression tracker.

Pierre-Louis Bossart, I noticed a report about a regression in
bugzilla.kernel.org that appears to be caused by the following change of
yours: d5263dbbd8af02 ("ASoC: SOF: Intel: don't ignore IOC interrupts
for non-audio transfers") [v6.10-rc1]

As many (most?) kernel developers don't keep an eye on the bug tracker,
I decided to write this mail. To quote from
https://bugzilla.kernel.org/show_bug.cgi?id=218961 :

> We have a Lenovo Thinkpad X1 Carbon Gen 10 in our lab and ever since
> 6.10.0-rc1 it has failed its first S2idle suspend, and has stopped
> getting S0iX on subsequent successful S2idle suspends. The issue in the
> first suspend fail is here in the audio driver (dmesg section shown):

Ciao, Thorsten (wearing his 'the Linux kernel's regression tracker' hat)

P.S.: let me use this mail to also add the report to the list of tracked
regressions to ensure it's doesn't fall through the cracks:
