linux-next: manual merge of the staging tree with the tty tree

Hi Greg,

Today's linux-next merge of the staging tree got a conflict in
drivers/staging/ipack/devices/ipoctal.c between commit 734cc1783816
("TTY: use tty_port_register_device") from the tty tree and commit
d04600679ba0 ("Staging: ipack/devices/ipoctal: simplify ipoctal_write_tty
()") from the staging tree.

I fixed it up (see below) and can carry the fix as necessary (no action
is required).
