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

From: Jarkko Nikula <jarkko.nikula at linux.intel.com>
commit f4821e8e8e957fe4c601a49b9a97b7399d5f7ab1 upstream.
Debugging showed Realtek RT5642 doesn't support autoincrementing writes so
driver should set the use_single_rw flag for regmap.
