TTY/Serial fixes for 4.18-rc3

Here are 5 fixes for the tty core and some serial drivers.

The tty core one fix some security and other issues reported by the
syzbot that I have taken too long in responding to (sorry Tetsuo!).  The
8350 serial driver fix resolves an issue of devices that used to work
properly stopping working as they shouldn't have been added to a
blacklist.

All of these have been in linux-next for a few days with no reported
issues.
