We're rather inconsistent in which error values we return to userspace
on failure. I want to unify the behaviour a bit and consistently return
ENOENT when mode object lookups fail. We already do that in a few places
but in most places we just return EINVAL.
I made a separate patch for each affected driver just in case there's some
magic meaning to the error values for certain drivers.
Ville Syrjälä (7):
drm: Consistently return -ENOENT when a mode object can't be found
drm: Return -ENOENT when a framebuffer can't be found
drm/gma500: Return -ENOENT when a mode object can't be found
drm/i915: Return -ENOENT when a mode object can't be found
drm/radeon: Return -ENOENT when a mode object can't be found
drm/vmwgfx: Return -ENOENT when a mode object can't be found
drm/vmwgfx: Return -ENOENT when a framebuffer can't be found
