Merge tag 'tty-3.9-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/tty
Pull tty/serial patches from Greg Kroah-Hartman: "Here's the big tty/serial driver patches for 3.9-rc1. More tty port rework and fixes from Jiri here, as well as lots of individual serial driver updates and fixes. All of these have been in the linux-next tree for a while." * tag 'tty-3.9-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/tty: (140 commits) tty: mxser: improve error handling in mxser_probe() and mxser_module_init() serial: imx: fix uninitialized variable warning serial: tegra: assume CONFIG_OF TTY: do not update atime/mtime on read/write lguest: select CONFIG_TTY to build properly. ARM defconfigs: add missing inclusions of linux/platform_device.h fb/exynos: include platform_device.h ARM: sa1100/assabet: include platform_device.h directly serial: imx: Fix recursive locking bug pps: Fix build breakage from decoupling pps from tty tty: Remove ancient hardpps() pps: Additional cleanups in uart_handle_dcd_change pps: Move timestamp read into PPS code proper pps: Don't crash the machine when exiting will do pps: Fix a use-after free bug when unregistering a source. pps: Use pps_lookup_dev to reduce ldisc coupling pps: Add pps_lookup_dev() function tty: serial: uartlite: Support uartlite on big and little endian systems tty: serial: uartlite: Fix sparse and checkpatch warnings serial/arc-uart: Miscll DT related updates (Grant's review comments) ... Fix up trivial conflicts, mostly just due to the TTY config option clashing with the EXPERIMENTAL removal.
