Merge tag 'regmap-3.4' into regmap-stride
regmap: Last minute bug fix for 3.4 This is a last minute bug fix that was only just noticed since the code path that's being exercised here is one that is fairly rarely used. The changelog for the change itself is extremely clear and the code itself is obvious to inspection so should be pretty safe. Conflicts: drivers/base/regmap/regmap.c (overlap between the fix and stride code)
