Subject: [PATCH 071/106] ASoC: max98088 - fix element type of the register cache.

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

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

From: Chih-Chung Chang <chihchung@...omium.org>

commit cb6f66a2d278e57a6c9d8fb59bd9ebd8ab3965c2 upstream.

The registers of max98088 are 8 bits, not 16 bits. This bug causes the
contents of registers to be overwritten with bad values when the codec
is suspended and then resumed.
