[PATCH 14/17] fbdev: Remove flag FBINFO_FLAG_DEFAULT from fbdev drivers

Thomas Zimmermann
2023-07-10T13:02:21Z

The flag FBINFO_FLAG_DEFAULT is 0 and has no effect, as struct
fbinfo.flags has been allocated to zero by framebuffer_alloc(). So
do not set it.

Flags should signal differences from the default values. After cleaning
up all occurences of FBINFO_FLAG_DEFAULT, the token can be removed.
