3.16.60-rc1 review patch. If anyone has any objections, please let me know.
------------------
From: Charles Keepax <ckeepax@xxxxxxxxxxxxxxxxxxxxx>
commit b8f9a03b741ddfdde4aa8b607fa7d88eb63a6338 upstream.
The current implementation is broken for regmaps that have a reg_stride,
since it doesn't take the stride into account. Correct this by using the
helper function to calculate the register offset.
Fixes: f01ee60fffa4 ("regmap: implement register striding")

[bwh: Backported to 3.16: Use simple multiplication instead of
regmap_get_offset()]
