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.

Not anything for this patch, but having this dubbed "onoff" instead of
"on" makes it really confusing.

Especially here. What does "!onoff" mean? If it were:
if (on)
sdio_uart_set_mctrl(port, TIOCM_DTR | TIOCM_RTS);
else
sdio_uart_clear_mctrl(port, TIOCM_DTR | TIOCM_RTS);
it would be a lot more clear.

Or "raise". That makes sense too and we call it as such in

Care to fix that up too?
