Subject: [PATCH 1/5] ASoC: cs53l30: Add missing regmap use_single config
Date: Tue, 11 May 2021 18:57:14 +0100	[thread overview]
Message-ID: <20210511175718.15416-1-ckeepax@opensource.cirrus.com> (raw)

This device requires single register transactions, this will
definely cause problems with the new device ID parsing which
uses regmap_bulk_read but might also show up in the cache sync
sometimes. Add the missing flags to the regmap_config.

Fixes: 4fc81bc88ad9 ("ASoC: cs53l30: Minor error paths fixups")
