Fix istallion build failure
Commits b02f5ad6a3ff5a1ee2a7b8ec6eee338de553b060 ("istallion: use tty_port") and a352def21a642133758b868c71bee12ab34ad5c5 ("tty: Ldisc revamp") broke the istallion driver. Fix the compile error and silence a warning. Signed-off-by: Wang Chen <wangchen@cn.fujitsu.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
