Fixes: f5aab0438ef1 ("regulator: pca9450: Fix enable register for LDO5")

FYI, you can have multiple fixes tag, and to be safe to not introduce regression
on some stable backport because the 2 patches are not back-ported at the same
time, better to have both the Fixes tags here.

No need to send a v5, the tag should be picked up from this email.
