[PATCH 0/7] drm: Return -ENOENT when objects can't be found

[ville.syrjala at linux.intel.com]

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.

      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
