Subject: [PATCH 19/26] ALSA: cs35l41: Do not print error when waking from hibernation

From: Stefan Binding <sbinding@...nsource.cirrus.com>

When waking from hibernation, it is possible for the function
which sends the wake command to fail initially, but after a
retry it will succeed. There is no need to print an error if
the initial attempts fail.
