[PATCH v3 07/13] tty: Convert ->dtr_rts() to take bool argument
Convert the raise/on parameter in ->dtr_rts() to bool through the
callchain. The parameter is used like bool. In USB serial, there
remains a few implicit bool -> larger type conversions because some
devices use u8 in their control messages.
In moxa_tiocmget(), dtr variable was reused for line status which
requires int so use a separate variable for status.
