From: Ville Syrjälä <ville.syrjala@linux.intel.com>

Another respin of the possible_clones/crtcs fixing.

Changes based on v2 review:
- introduce drm_mode_config_validate()
- WARN for possible_clones!=0 when the encoder
  itself isn't in the mask
- update the documentation to match the code

Other changes:
- sligth refactoring of the code to make it
  more consistent
- add a patch to fixup possible_crtcs too (might not
  be needed but included it just in case).

Cc: Thomas Zimmermann <tzimmermann@suse.de>
Cc: Daniel Vetter <daniel@ffwll.ch>

Ville Syrjälä (7):
  drm: Include the encoder itself in possible_clones
  drm/gma500: Sanitize possible_clones
  drm/exynos: Use drm_encoder_mask()
  drm/imx: Remove the bogus possible_clones setup
  drm: Validate encoder->possible_clones
  drm: Validate encoder->possible_crtcs
  drm: Allow drivers to leave encoder->possible_crtcs==0
