Subject: Re: [RESEND PATCH v5 6/6] ASoC: amd: Added ACP3x system resume and
runtime pm (fwd)
Line 179 needs to cleanup everything that needed to be cleaned up in the
previous error handling code (line 173) as well as adding an iounmap. But
maybe you could have used a devm function to avoid the need for the
iounmap.
Also functions should have blank lines between them. That is why this
report contains lots of function definitions, and not just the one with
the problem.
