Subject: ASoC: rt5640: Do not allow regmap to use bulk read-write operations
From: Jarkko Nikula <jarkko.nikula@xxxxxxxxxxxxxxx>
commit f4821e8e8e957fe4c601a49b9a97b7399d5f7ab1 upstream.
Debugging showed Realtek RT5642 doesn't support autoincrementing writes so
driver should set the use_single_rw flag for regmap.
