It's on top of my patch "auxdisplay: ht16k33: select CONFIG_FB_SYS_FOPS"
from a few days ago. I guess Robin expected you to have picked that
up, while you expected him to combine it with the new changes.

Robin, I think it's easier if you send the combined patch and
add "Reported-by: Arnd Bergmann <arnd@...db.de>", as Greg has
probably already droppped my earlier patch from his queue.
