Subject: [PATCH 1/2] drm/amdgpu: return early for preempt type BOs
Date: Fri, 25 Jun 2021 19:28:03 +0200	[thread overview]
Message-ID: <20210625172804.3193-1-nirmoy.das@amd.com> (raw)

Return early for AMDGPU_PL_PREEMPT 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.
