Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/ieee1394/linux1394-2.6

* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/ieee1394/linux1394-2.6:
  firewire: core: use more outbound tlabels
  firewire: core: don't update Broadcast_Channel if RFC 2734 conditions aren't met
  firewire: core: prepare for non-core children of card devices
  firewire: core: include linux/uaccess.h instead of asm/uaccess.h
  firewire: add parent-of-unit accessor
  firewire: rename source files
  firewire: reorganize header files
  firewire: clean up includes
  firewire: ohci: access bus_seconds atomically
  firewire: also use vendor ID in root directory for driver matches
  firewire: share device ID table type with ieee1394
  firewire: core: add sysfs attribute for easier udev rules
  firewire: core: check for missing struct update at build time, not run time
  firewire: core: improve check for local node
