FYI, this breaks the DT bindings. The relevant patches didn't get
reviewed nor run thru automated testing because their encoding was
'charset=y'[1]. (While email clients seem to just ignore that
encoding, patchwork and b4 do not.) linux-next is still broken and has
been since Mar 2[2]. v2 of the fixes[3] have been posted since Mar 9,
and still aren't in linux-next.

It doesn't have to be fixed in this PR, but it needs to be fixed
before rc1. Otherwise, no one can test their bindings using rc1. In
general, there's no reason fixes need to wait until after rc1 as
Chun-Kuang suggests[4].
