You didn't run this through scripts/get_maintainer.pl, did you? It would
also help to use the standard prefix ("drm/panel: ") because I end up
filtering for that occasionally in case somebody didn't Cc me on panel
patches.

I only came across this by accident, and it's going to miss 4.3 now.

Also two comments below...

I don't see a vendor prefix for QiaoDian XianShi Corporation in
Documentation/devicetree/bindings/vendor-prefixes.txt.

Can you also add .bpc = 8 above so that drivers that don't support the
.bus_format can still support this panel?

I'm pretty sure I did as you were the only one in the To: field.
Maybe you want to check your spam filter.

Looking again, I see that you did indeed. Not sure what I was looking at
before. I apologize.
