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
rest of the array..

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