Add process_read_urb to usb_serial_driver so that a driver can rely on the generic read (and throttle) mechanism but still do device specific processing of incoming data (such as adding tty_flags before pushing to line discipline). The default generic implementation handles sysrq for consoles but otherwise simply pushes to tty. Signed-off-by: Johan Hovold <jhovold@gmail.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
