Subject: [PATCH 2/4] ASoC: sunxi: Use {regmap/regmap_field}_{set/clear}_bits helpers
Date: Sat, 21 May 2022 07:27:33 -0700	[thread overview]
Message-ID: <180e70431e2.e6d0d6a445873.707989504680364975@zohomail.com> (raw)
In-Reply-To: <180e702a15f.e737e37e45859.3135149506136486394@zohomail.com>

From: Li Chen <lchen@ambarella.com>

Appropriately change calls to {regmap/regmap_field}_update_bits()
with {regmap/regmap_field}_set_bits()
and {regmap/regmap_field}_clear_bits() for improved readability.
