Subject: [PATCH] drm/amdgpu: Skip put_reset_domain if it doesnt exist
Date: Wed, 28 Sep 2022 14:22:29 -0400	[thread overview]
Message-ID: <20220928182229.14683-1-Vignesh.Chander@amd.com> (raw)

For xgmi sriov, the reset is handled by host driver and hive->reset_domain
is not initialized so need to check if it exists before doing a put.
