[PATCH] drm/i915: Reject the colorkey ioctls for primary and cursor planes

[PATCH] drm/i915: Reject the colorkey ioctls for primary and cursor planes

[ville.syrjala]

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

The legcy colorkey ioctls are only implemented for sprite planes, so
reject the ioctl for primary/cursor planes. If we want to support
colorkeying with these planes (assuming we have hw support of course)
we should just move ahead with the colorkey property conversion.

[PATCH i-g-t] tests: Add kms_legacy_colorkey

[ville.syrjala]

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

Add a quick test to make sure the legacy set colorkey ioctl only works
for sprite planes.

Since this is a simple test without subtests, using igt_fixture blocks
isn't necessary.
