[PATCH 3.14 061/114] ASoC: rt5640: Do not allow regmap to use bulk read-write operations

[Greg Kroah-Hartman]

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

------------------

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.
