Subject: [PATCH 18/26] ASoC: cs35l41: Move cs35l41 exit hibernate function into shared code
Date: Wed, 27 Apr 2022 16:07:12 +0100 [thread overview]
Message-ID: <20220427150720.9194-19-vitalyr@opensource.cirrus.com> (raw)
In-Reply-To: <20220427150720.9194-1-vitalyr@opensource.cirrus.com>
From: Stefan Binding <sbinding@opensource.cirrus.com>
CS35L41 HDA Driver will support hibernation using DSP firmware,
move the exit hibernate function into shared code so this can
be reused.
