* 'tty-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/tty-2.6:
  omap-serial: Allow IXON and IXOFF to be disabled.
  TTY: serial, document ignoring of uart->ops->startup error
  TTY: pty, fix pty counting
  8250: Fix race condition in serial8250_backup_timeout().
  serial/8250_pci: delete duplicate data definition
  8250_pci: add support for Rosewill RC-305 4x serial port card
  tty: Add "spi:" prefix for spi modalias
  atmel_serial: fix atmel_default_console_device
  serial: 8250_pnp: add Intermec CV60 touchscreen device
  drivers/serial/ucc_uart.c: Fix compiler warning
