Fully initialize detector_work work struct to avoid this kernel warning when lockdep is enabled:
===================================== WARNING: bad unlock balance detected! 6.5.0-rc5+ #687 Not tainted ------------------------------------- swapper/0/1 is trying to release lock (detector_work) at: [<000000004037e554>] __flush_work+0x60/0x658 but there are no more locks to release!
other info that might help us debug this: no locks held by swapper/0/1.
