Subject: [PATCH] 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")
