tty: serial: qcom_geni_serial: Allow mctrl when flow control is disabled
The geni set/get_mctrl() functions currently do nothing unless hardware flow control is enabled. Remove this arbitrary limitation. Suggested-by: Johan Hovold <johan@kernel.org> Fixes: 8a8a66a1a18a ("tty: serial: qcom_geni_serial: Add support for flow control") Signed-off-by: Matthias Kaehlcke <mka@chromium.org> Reviewed-by: Johan Hovold <johan@kernel.org> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
