From 18900ca65a8553edc608b6c9d518eb31e6c09ba1 Mon Sep 17 00:00:00 2001 From: Peter Hurley Date: Sat, 9 Apr 2016 17:06:48 -0700 Subject: tty: Replace TTY_IO_ERROR bit tests with tty_io_error() Abstract TTY_IO_ERROR status test treewide with tty_io_error(). NB: tty->flags uses atomic bit ops; replace non-atomic bit test with test_bit().
