This patch performs that cleanup for the hvsi driver. The hvsi driver is used only on IBM pSeries PowerPC boxes. The driver was originally written by Hollis Blanchard, who has delegated maintainership to me. So this my first and maybe only patch in this official new role, because this driver is otherwise bug-free :-) Alan: "Actually its also a bug fix, tty->ldisc should be locked by refcounting and the helpers do this for you."
