To: Greg KH <[EMAIL PROTECTED]>
Cc: David Brownell <[EMAIL PROTECTED]>, USB list <[email protected]>
Message-ID: <[EMAIL PROTECTED]>
This patch (as1030b) moves a del_timer_sync() call outside the scope of a
spinlock, where it could cause a deadlock, and adds a new
del_timer_sync() call for the new IAA watchdog timer (it was omitted
by mistake).
