This fixes the SND_PCI_QUIRK(...) of the TongFang PHxTxX1 barebone. This
fixes the issue of sound not working after s3 suspend.
When waking up from s3 suspend the Coef 0x10 is set to 0x0220 instead of
0x0020. Setting the value manually makes the sound work again. This patch
does this automatically.
While being on it, I also fixed the comment formatting of the quirk.

An educational question: Is there any, at least partial, documentation available on what these Coef values actually do
besides https://www.kernel.org/doc/html/v5.15/sound/hd-audio/realtek-pc-beep.html ?

Please try to put Fixes tag as this is a fix for the existing change.
The code change looks almost good, but just minor nitpicking:

The variable name is unnecessarily too long. Please use a shorter
one.

Try to keep the line in 80 column. It's OK to take a longer if it has
to be, but in a case like this, it doesn't need to be that long.

Unfortunately, no. It's a completely vendor-specific black magic.

Sorry, wasn't aware of this. I guess it's [PATCH Fixes] as the beginning of the subject line?

Wrong tab width in my editor so I didn't see it, fixed in v2.
Compiling and testing now.

No, the Fixes tag is another line you add around your Signed-off-by
line for indicating that that the patch is for fixing the given
commit. In your case, it'll be like
Fixes: dd6dd6e3c791 ("ALSA: hda/realtek: Add quirk for TongFang PHxTxX1")
HTH,

Thanks, that was indeed very helpful.
Sorry for still making noob mistakes.
