Subject: [PATCH v2 1/5] ASoC: cs35l41: Only disable internal boost
Date: Tue, 7 Feb 2023 16:25:22 +0000 [thread overview]
Message-ID: <20230207162526.1024286-2-lucas.tanure@collabora.com> (raw)
In-Reply-To: <20230207162526.1024286-1-lucas.tanure@collabora.com>
In error situations, only the internal boost case
should be disabled and re-enabled.
Also, for other boost cases re-enabling the boost
to the default internal boost config is incorrect.
Fixes: 6450ef559056 ("ASoC: cs35l41: CS35L41 Boosted Smart Amplifier")
