From afc5ab096581e1ad6e7e7d1533a6bbb1d2b12455 Mon Sep 17 00:00:00 2001 From: Peter Hurley Date: Sun, 10 Jan 2016 14:51:40 -0800 Subject: tty: Remove ASYNC_CLOSING The tty core no longer provides nor uses ASYNC_CLOSING; remove from tty_port_close_start() and tty_port_close_end() as well as tty drivers which open-code these state changes. Unfortunately, even though the bit is masked from userspace, its inclusion in a uapi header precludes removing the macro.
