Subject: [PATCH 08/15] ASoC: cs42l42: Fix channel width support
Date: Tue, 2 Mar 2021 17:04:47 +0000 [thread overview]
Message-ID: <20210302170454.39679-9-tanureal@opensource.cirrus.com> (raw)
In-Reply-To: <20210302170454.39679-1-tanureal@opensource.cirrus.com>
Remove the hard coded 32 bits width and replace with the correct width
calculated by params_width.
Signed-off-by: Lucas Tanure <tanureal@opensource.cirrus.com>
