Yeah, perhaps I could have expanded on the problem a bit more here.

Hopefully it's clear if you look at the cover letter, but the commit
referred to above should have added a new compatible for SA8540P which
uses the new supply so that the OS can determine when it should try to
look it up and when it is required.

The Fixes tag can also be dropped, I admit this is not clear-cut.

Spare me the rant. This was obviously a mistake from reusing and
manually amending a git-send-email command from shell history and
failing to notice that this series also should have been CCed the
devicetree list.
