+Subject: [PATCH 2007/2940] drm/amdgpu:Fix the unpin warning about csb buffer
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+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 amdgpu_bo_free_kernel in gfx_v9_0_sw_fini, or it will have unpin warning.
