Merge tag 'tty-3.7-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/tty

Pull TTY fixes from Greg Kroah-Hartman:
 "Here are some tty and serial driver fixes for your 3.7-rc1 tree.

  Again, the UABI header file fixes, and a number of build and runtime
  serial driver bugfixes that solve problems people have been reporting
  (the staging driver is a tty driver, hence the fixes coming in through
  this tree.)

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

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

* tag 'tty-3.7-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/tty:
  staging: dgrp: check return value of alloc_tty_driver
  staging: dgrp: check for NULL pointer in (un)register_proc_table
  serial/8250_hp300: Missing 8250 register interface conversion bits
  UAPI: (Scripted) Disintegrate include/linux/hsi
  tty: serial: sccnxp: Fix bug with unterminated platform_id list
  staging: serial: dgrp: Add missing #include <linux/uaccess.h>
  serial: sccnxp: Allows the driver to be compiled as a module
  tty: Fix bogus "callbacks suppressed" messages
  net, TTY: initialize tty->driver_data before usage
