+Subject: [PATCH 1849/4131] drm/amdgpu/sriov:fix page fault issue of driver
+ unload
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+bo_free on csa is too late to put in amdgpu_fini because that
+time ttm is already finished,
+Move it earlier to avoid the page fault.
