Message-ID: <20100316101951.GD5331@bicker> (raw)
drivers/staging/frontier/alphatrack.c +854 usb_alphatrack_disconnect()
845 /* if the device is not opened, then we clean up right now */
846 if (!dev->open_count) {
847 up(&dev->sem);
848 usb_alphatrack_delete(dev);
We free "dev" here.
849 } else {
850 dev->intf = NULL;
851 up(&dev->sem);
852 }
853
854 atomic_set(&dev->writes_pending, 0);
We use it here.
