- drm_atomic_helper_plane_check_update
- @plane: plane object to update
== plane_state->plane, so can be removed
- @state: drm plane state
rename to plane_state
- @min_scale: minimum @src:@dest scaling factor in 16.16 fixed point
- @max_scale: maximum @src:@dest scaling factor in 16.16 fixed point
- @can_position: is it legal to position the plane such that it
doesn't cover the entire crtc? This will generally
only be false for primary planes.
- @can_update_disabled: can the plane be updated while the crtc
is disabled?
If you look carefully at drm_plane_helper_check_update, can_update_disabled will be a noop, so remove this parameter.
plane_state->crtc != NULL iff plane_state->fb != NULL
