Subject: [PATCH] cpqphp: fix oops during unload without probe
Date: Mon, 27 Jun 2005 22:32:55 -0700 [thread overview]
Message-ID: <1119936775691@kroah.com> (raw)
In-Reply-To: <1119936774843@kroah.com>
[PATCH] cpqphp: fix oops during unload without probe
drivers/pci/hotplug/cpqphp_core.c calls cpqphp_event_start_thread()
in one_time_init(), which is called whenever the hardware is probed.
Unfortunately, cpqphp_event_stop_thread() is *always* called when
the module is unloaded. If the hardware is never probed, then
cpqphp_event_stop_thread() tries to manipulate a couple of
uninitialized mutexes.
