[PATCH] Char: mxser_new, remove unused stuff
- nobody waits on close_wait - ASYNC_SPLIT_TERMIOS is not set by anybody, so do not test this flag - process session and pgrp are useless information Signed-off-by: Jiri Slaby <jirislaby@gmail.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
