You're changing the ABI and trying to CC this to stable.  This is
obviously not at all OK, this would mean that if someone got a stable
update with this change the ABI break would mean that their existing
device tree would not work.  The code should be making every effort to
provide a stable ABI over new kernel releases, never mind within a
stable point release.
