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...

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