Pull TTY/serial fixes from Greg Kroah-Hartman:
 "Here are some tty/serial driver fixes for 3.9.

  The big thing here is the fix for the huge mess we caused renaming the
  8250 driver accidentally in the 3.7 kernel release, without realizing
  that there were users of the module options that suddenly broke.  This
  is now resolved, and, to top the injury off, we have a backwards-
  compatible option for those users who got used to the new name since
  3.7.  Ugh, sorry about that.

  Other than that, some other minor fixes for issues that have been
  reported by users."
