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
