Can you please update the commit message to fix the following warning:

Please use git commit description style 'commit <12+ chars of sha1> 
("<title line>")' - ie: 'commit fe141cedc433 ("drm/imx: pd: Use bus 
format/flags provided by the bridge when available")'

Also, collect the AB from Boris and TB from Max.

I can also fix it up for you while applying if that's OK with you.
