Pull tty/serial driver update from Greg Kroah-Hartman:
 "Here's the big tty/serial driver merge request for 3.10-rc1

  Once again, Jiri has a number of TTY driver fixes and cleanups, and
  Peter Hurley came through with a bunch of ldisc fixes that resolve a
  number of reported issues.  There are some other serial driver
  cleanups as well.

  All of these have been in the linux-next tree for a while"
