[PATCH 3.12 082/142] ASoC: rt5640: Do not allow regmap to use bulk read-write operations

[Jiri Slaby]

From: Jarkko Nikula <jarkko.nikula@xxxxxxxxxxxxxxx>

3.12-stable review patch.  If anyone has any objections, please let me know.

===============

commit f4821e8e8e957fe4c601a49b9a97b7399d5f7ab1 upstream.

Debugging showed Realtek RT5642 doesn't support autoincrementing writes so
driver should set the use_single_rw flag for regmap.
