Dan Williams ba2d8ce9db cdc-acm: implement TIOCSSERIAL to avoid blocking close(2) ... Some devices (ex Nokia C7) simply don't respond at all when data is sent to some of their USB interfaces. The data gets stuck in the TTYs queue and sits there until close(2), which them blocks because closing_wait defaults to 30 seconds (even though the fd is O_NONBLOCK). This is rarely desired. Implement the standard mechanism to adjust closing_wait and let applications handle it how they want to. See also 02303f7337 for usb_wwan.c.
