The problem description from Arnd to an outsider like me sounded like
this is something that should be fixed rather sooner than later in
mainline. Am I wrong with that? If not: will this be heading to Linus
soon? Just wondering, as the fix seems to be a in "for-next" branch[1]
of the nvmem repo and not in a "fixes" branch.

Or am I missing something here?
