From 6776a2f07924192fd168bdceb1a00d10630edb4d Mon Sep 17 00:00:00 2001 From: Jiri Slaby Date: Mon, 2 Apr 2012 13:53:50 +0200 Subject: [PATCH] TTY: isdn, remove ISDN_ASYNC_* flags They are the same as TTY ones. So there is no need to redefine them. Remove ISDN_ASYNC_* and use only ASYNC_*. Except the MAGIC number, of course. While we are there, remove also the SERIAL_TYPE flags which are unused. Perhaps we should move the ASYNC flags from serial.h to tty.h given they are used by the tty layer and tty drivers, not only serial?
