Merge tag 'tty-3.8-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/tty

Pull TTY/Serial merge from Greg Kroah-Hartman:
 "Here's the big tty/serial tree set of changes for 3.8-rc1.

  Contained in here is a bunch more reworks of the tty port layer from
  Jiri and bugfixes from Alan, along with a number of other tty and
  serial driver updates by the various driver authors.

  Also, Jiri has been coerced^Wconvinced to be the co-maintainer of the
  TTY layer, which is much appreciated by me.

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

  Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>"

Fixed up some trivial conflicts in the staging tree, due to the fwserial
driver having come in both ways (but fixed up a bit in the serial tree),
and the ioctl handling in the dgrp driver having been done slightly
differently (staging tree got that one right, and removed both
TIOCGSOFTCAR and TIOCSSOFTCAR).
