Public bug reported:

[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.
