[SRU][OEM-5.10][PATCH 0/1] alsa/realtek: extend the delay time in the determine_headset_type for a Dell AIO

[Hui Wang]

BugLink: https://bugs.launchpad.net/bugs/1920747

Dell waited for the fix for a long time, today the fix is accepted by
upstream, I sent it to oem-5.10 kernel, and this patch is CCed to
stable, other ubuntu kernels will merge this fix with stable update.

[Impact]
Users plug a headset to this AIO and select headset-mic from UI, but
can't record any sound from the headset-mic.

[Fix]
The root cause is the driver return a wrong type of the headset, need
to add more delay in the determine_headset_type(), so backport that
patch to ubuntu kernel.

[Test]
Booting the system with patched kernel, plug headset and select
headset-mic from UI, could record sound from headset-mic, we tested
more than 10 times, all worked well.


[Where problems could occur]
This could make the user experience a small delay from pop-up dialogue
when plugging a headset, but the delay is less than 1s and the delay
is not much longer than other codecs, QA think it is acceptable.
