----------------------------------------------------------------
TTY/Serial fixes for 5.0-rc6

Here are some small tty and serial fixes for 5.0-rc6.

Nothing huge, just a few small fixes for reported issues.  The speakup
fix is in here as it is a tty operation issue.

All of these have been in linux-next for a while with no reported
problems.
