Subject: [PATCH 3.18 020/151] ASoC: rt5670: Set use_single_rw flag for regmap

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

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

From: Bard Liao <bardliao@...ltek.com>

commit 92b133f251b5f914f3ed28bc83e5b7a40d4e22ed upstream.

RT5670 doesn't support auto incrementing writes so driver should
set the use_single_rw flag for regmap.
