Merge tag 'tty-3.6' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/tty

Pull TTY changes from Greg Kroah-Hartman:
 "As we skipped the merge window for 3.6-rc1 for the tty tree,
  everything is now settled down and working properly, so we are ready
  for 3.7-rc1.  Here's the patchset, it's big, but the large changes are
  removing a firmware file and adding a staging tty driver (it depended
  on the tty core changes, so it's going through this tree instead of
  the staging tree.)

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

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

Fix up more-or-less trivial conflicts in
 - drivers/char/pcmcia/synclink_cs.c:
    tty NULL dereference fix vs tty_port_cts_enabled() helper function
 - drivers/staging/{Kconfig,Makefile}:
    add-add conflict (dgrp driver added close to other staging drivers)
 - drivers/staging/ipack/devices/ipoctal.c:
    "split ipoctal_channel from iopctal" vs "TTY: use tty_port_register_device"
