Oleg Nesterov 1e4597e8f0 V4L/DVB (5818): CinergyT2: fix flush_workqueue() vs work->func() deadlock ... Spotted and tested by Thomas Sattler <tsattler@gmx.de>. cinergyT2.c does cancel_delayed_work() + flush_scheduled_work() while holding cinergyt2->sem. This leads to deadlock because work->func() needs the same mutex to complete. Another bug is that this code in fact can't reliably stop the re-arming delayed_work. Convert this code to use cancel_rearming_delayed_work() and move it out of ->sem. Another mutex, ->wq_sem, was added to protect against the concurrent open/resume. This patch is a horrible hack to fix the lockup which happens in practice. As Dmitry Torokhov pointed out this driver has other problems and needs further changes.
