Subject: [PATCH 3.19.y-ckt 063/156] ASoC: arizona: Fix gain settings of FLL in free-run mode

3.19.8-ckt8 -stable review patch.  If anyone has any objections, please let me know.

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

From: Nikesh Oswal <Nikesh.Oswal@...fsonmicro.com>

commit 1cf5a330c05ae37a0a98ac7c9800a6f50d5579ec upstream.

The wrong register was used to set the gain of ref loop, when changing
the FLL output on an active FLL. This patch corrects the offset of the
gain register.
