[Intel-gfx] [CI 18/26] drm/i915: Remove highly confusing i915_gem_obj_ggtt_pin()

Chris Wilson chris at chris-wilson.co.uk
Thu Aug 4 07:33:07 UTC 2016


Since i915_gem_obj_ggtt_pin() is an idiom breaking curry function for
i915_gem_object_ggtt_pin(), spare us the confusion and remove it.
Removing it now simplifies later patches to change the i915_vma_pin()
(and friends) interface.

v2: Add a redundant GEM_BUG_ON(!view) to
i915_gem_obj_lookup_or_create_ggtt_vma()
