From: Alan Stern Date: Thu, 10 Jan 2008 21:43:15 +0000 (-0500) Subject: USB: EHCI: move del_timer_sync calls outside spinlocked region X-Git-Tag: v2.6.25-rc1~1075^2~30 X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=f8fa7571a928d6d0e1b7444b0ea69ec7dc7db3b6;p=linux-2.6 USB: EHCI: move del_timer_sync calls outside spinlocked region 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).
