Hi Arun

Fixes generally means something explodes, throws an Opps, userspace
does the wrong thing. Documentation/process/stable-kernel-rules.rst
says:

 - It must fix a real bug that bothers people (not a, "This could be a
   problem..." type thing).

Please explain how this is a real problem and what people it bothers.

I also don't see any attempt to keep backwards compatibility with
older device tree blobs. Is it intentional you will break such old
blobs?

Thanks
	Andrew
