From 8a612b2d2e53dc0b869344e5558271b0d7fd4a23 Mon Sep 17 00:00:00 2001 From: Jonathan Cavitt Date: Mon, 7 Aug 2023 14:19:55 +0200 Subject: [PATCH] drm/i915/gt: Simplify shmem_create_from_object map_type selection The object pin created for shmem_create_from_object is just a single use mapping with the sole purpose of reading the contents of the whole object in bulk. And the whole source object is also even a throw-away. Ergo, the additional logic required by i915_coherent_map_type can be safely dropped and simplified.
