USB: ueagle-atm: use system_wq instead of dedicated workqueues
With cmwq, there's no reason to use separate workqueues. Drop uea_softc->work_q and use system_wq instead. The used work item is sync flushed on driver detach. Signed-off-by: Tejun Heo <tj@kernel.org> Cc: Stanislaw Gruszka <stf_xl@wp.pl> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
