-Subject: [PATCH] drm/gud: Free buffers on device removal

-[ drm-misc commit f8ac863b6a93863334cefb94285daaa6617381b5 ]
-
-Free transfer and compression buffers on device removal instead of at
-DRM device removal time. This ensures that the usual 2x8MB buffers are
-released when the device is unplugged and not kept around should
-userspace keep the DRM device fd open.
-
-At least Ubuntu 20.04 doesn't release the DRM device on unplug.
-
-The damage_lock mutex is not destroyed because it is used outside the
-drm_dev_enter/exit block in gud_pipe_update(). AFAICT it's possible for
-an open fbdev descriptor to trigger a commit after the USB device is gone.
-
-v2: Don't destroy damage_lock
