Log:
MFC rev. 1.320:
The wakeup() line from the rev. 1.319 is wrong and reintroduces
a panic race on module unload. The wakeup() is internal to
kproc_exit/kthread_exit. The correct fix is to fix the msleep() in
detach to sleep on fdc->fdc_thread instead of &fdc->fdc_thread.
MFC rev. 1.319:
Wakeup the thread doing the fdc_detach() when the fdc worker thread exits [1].
Write access to the write-protected floppy shall call device_unbusy() to
pair the device_busy() in the fd_access() [2].
