[igt-dev] [PATCH i-g-t v3 10/14] igt: fb: Rework YUV i915 allocation path

[Maxime Ripard]

We only need to allocate a buffer using the GEM API when we're in the
condition that we currently test, and that we're running on i915.

All the other cases can be handled by a fallback to a dumb buffer
allocation. Let's simplify the code a bit to reflect that.
