[Bug 221637] Regression for Intel Corporation Device a876 (rev 10)

--- Comment #9 from Bianca Fürstenau (furstenau+kernelbugWGvWw1PW1l@posteo.net) ---
I applied the patch and it mostly worked.

Quick note: I was unable to figure out how to non-manually get a patch file
from the googlesource site and this incurred several hours of delay while I did
something else before I had the idea of trying to find the patch on kernel.org:
https://git.kernel.org/pub/scm/linux/kernel/git/bluetooth/bluetooth-next.git/patch/?id=5917dd39db2bfc8b1b4c6ea8ed99adb4badef707

When I applied the patch to 7.0.11, the Bluetooth worked with the current
firmware and the dmesg logs looked the same as with the old firmware except for
timings and version identifiers. When I applied the patch to 7.0.12, the
Bluetooth still worked but there were a lot of gp1 mailbox interrupts and new
warnings in the dmesg logs. This seems unexpected to me, but if it seems
expected to Kiran et al., I do not have any further issue with this. If it
seems unexpected to you, too, it might warrant further investigation.

Am I seeing correctly that the patch is already in 7.1.0? If so, it seems
unnecessary to revert anything for me as my understanding of the release
strategy of NixOS for the configuration I am running is that my next kernel
will be 7.1.0 anyway. If I am wrong about that, the consequence is only that
applying updates takes me an hour instead of a few minutes at most if one of
the updates was to the kernel. Definitely quite annoying, but also not terribly
prohibitive, as the device stays usable during the update process. (Still,
nothing I would look forward to doing a dozen times until 7.2.0 releases or
something.)
