Hi all,

After merging the tty tree, today's linux-next build (arm
multi_v7_defconfig) failed like this:

Caused by commit

c550f01c810f ("serial:serial_core: Allow use of CTS for PPS line discipline")

Looks like a suprise from some "interesting" previous development.

I have used the tty tree from next-20181003 for today.
