Absolutely agreed. It's useful information even if we don't plan on
backporting. Note that some staging fixes do get backported but
I'm adding a note to most things on this driver to say don't bother!
It's too far from 'good'. Great to have multiple people working on
sorting that though!
If you and Shreeya could review each others patches that would be
cool. I do have one of these, but I'm usually too lazy to actually
dig it out to test if there are others who are working with it
