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:
  ieee1394: schedule for removal
  firewire: core: use separate timeout for each transaction
  firewire: core: Fix tlabel exhaustion problem
  firewire: core: make transaction label allocation more robust
  firewire: core: clean up config ROM related defined constants
  ieee1394: mark char device files as not seekable
  firewire: cdev: mark char device files as not seekable
  firewire: ohci: cleanups and fix for nonstandard build without debug facility
  firewire: ohci: wait for PHY register accesses to complete
  firewire: ohci: fix up configuration of TI chips
  firewire: ohci: enable 1394a enhancements
  firewire: ohci: do not clear PHY interrupt status inadvertently
  firewire: ohci: add a function for reading PHY registers
