[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
