From 2d68655d15bc99981394f7caa769a14b03cac131 Mon Sep 17 00:00:00 2001 From: Peter Hurley Date: Sat, 9 Apr 2016 17:53:23 -0700 Subject: tty: Replace ASYNC_CHECK_CD and update atomically Replace ASYNC_CHECK_CD bit in the tty_port::flags field with TTY_PORT_CHECK_CD bit in the tty_port::iflags field. Introduce helpers tty_port_set_check_carrier() and tty_port_check_carrier() to abstract the atomic bit ops.
