usb-serial: begin switching to ->[sg]et_serial()
add such methods for usb_serial_driver, provide tty_operations ->[sg]et_serial() calling those. For now the lack of methods in driver means ENOIOCTLCMD from usb-serial ->[sg]et_serial(), making tty_ioctl() fall back to calling ->ioctl(). Once all drivers are converted, we'll be returning -ENOTTY instead, completing the switchover. Reviewed-by: Johan Hovold <johan@kernel.org> Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
