From e8a6ca808c5ed1e2b43ab25f1f2cbd43a7574f73 Mon Sep 17 00:00:00 2001 From: Matthias Kaehlcke Date: Fri, 18 Jan 2019 16:23:05 -0800 Subject: 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.
