We have a few more flags that are unused - should they be nuked too?
FBINFO_HWACCEL_FILLRECT
FBINFO_HWACCEL_ROTATE
FBINFO_HWACCEL_XPAN
Unused as in no references from fbdev/core/*
I would rather see one series nuke all unused FBINFO flags in one go.
Assuming my quick grep are right and the above can be dropped.
Sam
