Unsure if line-length for commit messages has been extended to 100 as it 
was the case for code parts but this line certainly exceeds default.

Are these two tags meaningful for upstream kernel?

We usually start from 'i' when it comes to choosing iteration-variable 
names.

Suggesting to move comment one line up as you ideally want to explain 
the reasoning behind if-statement, not the actual execution statement.

Once that is done, both parenthesis can be dropped.

Same applies here.

Pretty sure this two lines could be combined - does not exceed 
100character limit.

Please keep the newline between these two conditional blocks. A new 
if-statement usually translates to new thought and it is good to 
separate those.

This indentation seems off. Though it seems the same applies for the

For 'forward compatibility' with possible changes to struct 
snd_soc_acpi_codecs, I'd advise appending comma at the end of the line.

There's certainly no reason not to wrap this one.  Even for code it's
not something to actively aim for.

I don't think we need this for upstream?

this could be const. We didn't do it for previous codecs but that was a
miss. I'll send a patch for the max98373
