NET: irda, remove unnecessary checks
Stanse found a potential null dereference in ircomm_tty_close and ircomm_tty_hangup. There is a check for tty being NULL, but it is dereferenced earlier. But it is bogus, the tty cannot be NULL, so remove the !tty checks. Signed-off-by: Jiri Slaby <jslaby@suse.cz> Cc: Samuel Ortiz <samuel@sortiz.org> Cc: "David S.
