[PATCH 0/4] drm/i915: Abort if crtc/plane init fails

[ville.syrjala@linux.intel.com]

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

I recently realized that we can't really continue with loading the driver
if we fail to initialize some of the crtcs or planes. So this series makes
us fail the load in those cases. The failures would be due to kmalloc()
failing anyway, so doesn't seem too drastic to abort entirely in that case.

I also reorder things so that we'll initialize the planes in an order that
matches the new rules for handling zpos conflicts between the planes. We don't
expose the zpos property yet, but I have some preliminary patches for that
as well sitting around in a branch. Actually only VLV, CHV and pre-g4x can
dynamically adjust the zpos of the planes, for the rest it's entirely fixed.

And finally I do a bit of house cleaning in the sprite init code.
