Merge branch 'tty-next' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/tty
* 'tty-next' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/tty: (79 commits) TTY: serial_core: Fix crash if DCD drop during suspend tty/serial: atmel_serial: bootconsole removed from auto-enumerates Revert "TTY: call tty_driver_lookup_tty unconditionally" tty/serial: atmel_serial: add device tree support tty/serial: atmel_serial: auto-enumerate ports tty/serial: atmel_serial: whitespace and braces modifications tty/serial: atmel_serial: change platform_data variable name tty/serial: RS485 bindings for device tree TTY: call tty_driver_lookup_tty unconditionally TTY: pty, release tty in all ptmx_open fail paths TTY: make tty_add_file non-failing TTY: drop driver reference in tty_open fail path 8250_pci: Fix kernel panic when pch_uart is disabled h8300: drivers/serial/Kconfig was moved parport_pc: release IO region properly if unsupported ITE887x card is found tty: Support compat_ioctl get/set termios_locked hvc_console: display printk messages on console. TTY: snyclinkmp: forever loop in tx_load_dma_buffer() tty/n_gsm: avoid fifo overflow in gsm_dlci_data_output tty/n_gsm: fix a bug in gsm_dlci_data_output (adaption = 2 case) ... Fix up Conflicts in: - drivers/tty/serial/8250_pci.c Trivial conflict with removed duplicate device ID - drivers/tty/serial/atmel_serial.c Annoying silly conflict between "specify the port num via platform_data" and other changes to atmel_console_init
