Bug description:
[SRU Justification]
[Impact]
The two CS42L42 codecs fails to output sound after runtime resume since
kernel 6.3-rc1.
[Fix]
Backport a fix from Cirrus on
https://patchwork.kernel.org/project/alsa-devel/patch/20230904160033.908135-1-vita...@opensource.cirrus.com/.
[Test]
1. Power on the laptop
2. Wait for at least 1 minute after login Ubuntu
3. Go to the audio settings and press the audio output test button
4. Verify if there's any audio output
[Where problems could occur]
It only happens on particular audio codec and clarified by the vendor that
the delay during resume will suffice after fix across different versions of
kernels.
