Subject: [PATCH] regmap: Correct offset handling in regmap_volatile_range
Git-commit: b8f9a03b741ddfdde4aa8b607fa7d88eb63a6338
Patch-mainline: v4.17-rc1
References: bsc#1051510

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.
