Confirmed. Reverting the merge (as far as it can be reverted) gets me
booting N950 with working display. (With 906dde applied, backlight
goes turns on, so it looks like display driver is initialized, but
then machine is killed, probably by watchdog).

AFAICT N950 display never worked on mainline; I'm using Sebastian's
patches to get it to work.
