When testing bind/unbind on r8a7791/koelsch: WARNING: CPU: 1 PID: 697 at lib/debugobjects.c:329 debug_print_object+0x8c/0xb4 ODEBUG: free active (active state 0) object type: timer_list hint: delayed_work_timer_fn+0x0/0x10 This happens if the workqueue runs after the device has been unbound. Fix this by cancelling any queued work during remove.
