[PATCH -next 6/9] cris: Remove obsolete ASYNC_SPLIT_TERMIOS behavior
From: Peter Hurley
Date: Wed Nov 05 2014 - 12:28:05 EST
ASYNC_SPLIT_TERMIOS behavior is a remnant of the long-dead /dev/cuaXX
callout device. Split termios handling was removed tree-wide in v2.5.71 by:
commit 99a21edebbfd8c29e39ee7fcc8a1ffa423657290
Author: Alexander Viro <viro@xxxxxxxxxxxxxxxx>
Date: Wed Jun 11 07:41:28 2003 -0700
[PATCH] tty_driver refcounting
killed the last remnants of callout stuff - we don't need to mess with
storing termios privately anymore.
which pre-dated the re-introduction into the cris serial driver
in v2.6.7 by:
commit 311a5ffeda8ccb3f1f3840069f37234e043092d4
