[PATCH] More !tty cleanups in drivers/char
Another bunch of checks in the char drivers .put_char() and .write() routines, where tty can never be NULL. This patch removes these checks to save some code. Coverity choked at those with the following bug ids: isicom.c 767, 766 specialix.c 773, 774 synclink_cs.c 779, 781 synclink_gt.c 784, 785 synclinkmp.c 784, 785 Signed-off-by: Eric Sesterhenn <snakebyte@gmx.de> Cc: Paul Fulghum <paulkf@microgate.com> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
