From 3dfb2d6b489f7f1a627774f84a6341c18785f43f Mon Sep 17 00:00:00 2001 From: Imre Deak Date: Wed, 20 Oct 2021 22:51:30 +0300 Subject: [PATCH] drm/i915: Add tiling attribute to the modifier descriptor MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Add a tiling atttribute to the modifier descriptor, which let's us get the tiling without listing the modifiers twice. v1-v2: Unchanged. v3: - Initialize .tiling to I915_TILING_NONE explicitly (Ville) - Move from previous patch lookup_modifier() to here, where it's first used.
