Subject[PATCH 2/4] regmap: Correct offset handling in regmap_volatile_range
Date
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")
