Merge branch 'ieee1394-removal' of git://git.kernel.org/pub/scm/linux/kernel/git/ieee1394/linux1394-2.6
* 'ieee1394-removal' of git://git.kernel.org/pub/scm/linux/kernel/git/ieee1394/linux1394-2.6:
ieee1394: remove the old IEEE 1394 driver stack
ieee1394: move init_ohci1394_dma to drivers/firewire/
Fix trivial change/delete conflict: drivers/ieee1394/eth1394.c is
getting removed, but was modified by the networking merge.
