From 5604a98e2f95d6221852960a3363588f40d78e22 Mon Sep 17 00:00:00 2001 From: Peter Hurley Date: Sat, 9 Apr 2016 17:53:21 -0700 Subject: tty: Replace ASYNC_CTS_FLOW bit and update atomically Replace ASYNC_CTS_FLOW bit in the tty_port::flags field with TTY_PORT_CTS_FLOW bit in the tty_port::iflags field. Add tty_port_set_cts_flow() helper to abstract the atomic bit ops.
