^^^^
If I'm not mistaken here, our options are to remove the return or just
leave this as is. IMO I think this is fine as is.

Did you build this change?
Exactly what tool reported a problem with this code and what was the
exact error?

Hello Greg,
I've run the checkpatch.pl script on audio_code.c:
> ./scripts/checkpatch.pl --file --terse
> drivers/staging/greybus/audio_codec.c
and got the following warning:
> drivers/staging/greybus/audio_codec.c:1032: WARNING: void function
> return statements are not generally useful
As Brian wrote, we can either remove the return or leave it as is, so my
"changes" can be ignored. This is not a coding style issue and I should
have been more clear on the commit message. I apologize for the mistake.
Thank you and @Brian for taking the time to reply.
Kind regards,
Senthu
