Subject: [PATCH v4 05/11] ASoC: jz4740-i2s: Use FIELD_PREP() macros in hw_params callback
Date: Fri, 8 Jul 2022 17:02:38 +0100 [thread overview]
Message-ID: <20220708160244.21933-6-aidanmacdonald.0x0@gmail.com> (raw)
In-Reply-To: <20220708160244.21933-1-aidanmacdonald.0x0@gmail.com>
Get rid of a couple of macros and improve readability by using
FIELD_PREP() and GENMASK() for the sample size setting.
Acked-by: Paul Cercueil <paul@crapouillou.net>
