Thanks, but the other points don't seem corrected (the
spec->mic_mute_led_polarity setup and the unneeded comma removal)?

Also, please note that the description here would be taken as the
commit log as-is, so you'd better to consider what's written there;
e.g. you need no greeting or mentioning that it's your first patch :)
Just describe the problem and the fix.  And, the references can be put
around the signed-off-by line like:
BugLink: https://bugzilla.kernel.org/show_bug.cgi?id=213953

Last but not least, as Geraldo suggested, it'd be helpful to put "v2"
suffix in the subject line indicating it's a revised patch.


thanks,

Takashi
