Subject: [PATCH 1/4] ASoC: cs42l42: Remove redundant writes to DETECT_MODE
Date: Tue, 16 Nov 2021 16:26:46 +0000 [thread overview]
Message-ID: <20211116162652.45225-3-rf@opensource.cirrus.com> (raw)
In-Reply-To: <20211116162652.45225-1-rf@opensource.cirrus.com>
There are multiple places where DETECT_MODE is included in a register
write, but in every case it is written as 0. Removing these redundant
writes makes the code less cluttered and also makes it obvious that
DETECT_MODE is never changed.
A single initialization to 0 is added to cs42l42_setup_hs_type_detect().
