regulator: lp872x: Kill _rdev_to_offset() function
There is only one user calling _rdev_to_offset() function. Remove _rdev_to_offset() makes the code simpler. Signed-off-by: Axel Lin <axel.lin@ingics.com> Acked-by: Milo(Woogyom) Kim <milo.kim@ti.com> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
