Subsystem:
drm drivers, drm drivers and misc gpu patches, drm drivers for gma500 (poulsbo, moorestown and derivative chipsets), radeon and amdgpu drm drivers, the rest · Maintainers:
David Airlie, Simona Vetter, Maarten Lankhorst, Maxime Ripard, Thomas Zimmermann, Patrik Jakobsson, Alex Deucher, Christian König, Linus Torvalds
The flag FBINFO_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_DEFAULT, the token can be removed.
