[PATCH 4.20 40/88] tty: serial: qcom_geni_serial: Allow mctrl when flow control is disabled

[Greg Kroah-Hartman]

4.20-stable review patch.  If anyone has any objections, please let me know.

------------------

[ Upstream commit e8a6ca808c5ed1e2b43ab25f1f2cbd43a7574f73 ]

The geni set/get_mctrl() functions currently do nothing unless
hardware flow control is enabled. Remove this arbitrary limitation.
