Subject: [PATCH] drm/amdgpu: Don't need to call csb_vram_unpin
Date: Mon, 27 May 2019 16:41:27 +0800	[thread overview]
Message-ID: <1558946487-18034-1-git-send-email-Emily.Deng@amd.com> (raw)

As it will destroy clear_state_obj, and also will
unpin it in the gfx_v9_0_sw_fini, so don't need to
call csb_vram unpin in gfx_v9_0_hw_fini, or it will
have unpin warning.

v2: For suspend, still need to do unpin
