Subject: [PATCH v2 1/2] drm/amdgpu: return early for non-TTM_PL_TT type BOs
Date: Tue, 29 Jun 2021 09:36:28 +0200 [thread overview]
Message-ID: <20210629073629.3069-1-nirmoy.das@amd.com> (raw)
Return early for non-TTM_PL_TT BOs so that we don't pass
wrong pointer to amdgpu_gtt_mgr_has_gart_addr() which assumes
ttm_resource argument to be TTM_PL_TT type BO's.
v2: merge if-conditions
