[alsa-devel] [PATCH] regulator: Update LDO2 for WM8958

[Mark Brown]

LDO2 has a slightly different range of supported voltages on WM8958
so update the selector<->voltage mappings to match.

As the WM8958 support is currently sitting in the ASoC tree for the next
merge window this should get merged that way.  I've done some test
merges here and git seems to be able to figure out the overlaps with the
code in your tree so are you OK with applying to ASoC?
