From: Daniel Vetter Date: Tue, 14 Apr 2015 15:35:25 +0000 (+0200) Subject: drm/i915: Unduplicate i915_ggtt_unbind/bind_vma X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=d369d2d9683dd98afbc7a37c1119d7a317790c47;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git drm/i915: Unduplicate i915_ggtt_unbind/bind_vma ggtt_bind/unbind_vma already has checks for aliasing ppgtt or not, there's nothing else magic they do. Resurrect i915_ggtt_insert_entries to make the reuse possibel.
