Subject: [PATCH v4 12/16] ALSA: hda: cs35l41: Reorganize log for playback actions
Date:   Thu, 17 Mar 2022 09:31:16 +0000
Message-ID: <20220317093120.168534-13-tanureal@opensource.cirrus.com>

For each case, only log the last regmap access, so it doesn't get
overwritten, and as all regmap access should show the same issues
logging the last one should be enough.
Change to dev_err to log this error.

Also, differentiate between a regmap access failure and invalid
playback action.
