USB: make intf.pm_usage an atomic_t This patch (as1260) changes the pm_usage_cnt field in struct usb_interface from an int to an atomic_t. This is so that drivers can invoke the usb_autopm_get_interface_async() and usb_autopm_put_interface_async() routines without locking and without fear of corrupting the pm_usage_cnt value.
