[PATCH 2/2] USB : serial : invoke dcd_change ldisc's handler.

2013-09-16 Thread Paul Chavent
The DCD pin of the serial port can receive a PPS signal. By calling the port line discipline dcd handle, this patch allow to monitor PPS through USB serial devices. However the performance aren't as good as the uart drivers, so document this point too. Signed-off-by: Paul Chavent
