Merge tag 'regulator-fix-v6.6-merge-window' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regulator
Pull regulator fixes from Mark Brown:
"A couple of fixes that came in during the merge window, both driver
specific - one for a bug that came up in testing, one for a bug due
to a misreading of the datasheet"
