Bluetooth: hci_ldisc: Fix tty_set_termios() return value assumptions
tty_set_termios() never returns anything else than 0. Make the debug prints to look directly into the new termios instead to check CRTSCTS state. Signed-off-by: Ilpo Järvinen <ilpo.jarvinen@linux.intel.com> Signed-off-by: Luiz Augusto von Dentz <luiz.von.dentz@intel.com>
