task #29077503
commit 3c42e198e668e4040ef5cf3ad60d57765abc08a4 upstream
Registering our parent resource will fail if any memory is still present
(e.g., because somebody unloaded the driver and tries to reload it). No
need for the manual check.

Move our "unplug all" handling to after registering the resource.
