Subject: [PATCH] ASoC: cs53l30: Use the devm_clk_get_optional() helper
Date: Sat, 20 May 2023 16:54:06 +0200	[thread overview]
Message-ID: <3219effee5c7f190530bdb1ef8ec35cb142e3611.1684594433.git.christophe.jaillet@wanadoo.fr> (raw)

Use devm_clk_get_optional() instead of hand writing it.
This saves some LoC and improves the semantic.
