[PATCH] drivers/base/bus.c: fix iteration in driver_detach()
With 2.6.11 and 2.6.12-rc2 (and perhaps a few versions before) usb drivers for multi-interface devices, which do usb_driver_release_interface() in their disconnect(), make rmmod hang. It turns out to be due to a bug in drivers/base/bus.c:driver_detach(), that iterates over the list of attached devices with list_for_each_safe() under an assumption that device_release_driver() only releases the current device, while it may also call device_release_driver() for other devices on the same list. The following patch fixes it. Please consider applying. Signed-off-by: Roman Kagan <rkagan@mail.ru> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
