Merge tag 'firewire-updates' of git://git.kernel.org/pub/scm/linux/kernel/git/ieee1394/linux1394
Pull firewire updates from Stefan Richter: - Small fixes and optimizations. - A new sysfs attribute to tell local and remote nodes apart. Useful to set special permissions/ ownership of local nodes' /dev/fw*, to start daemons on them (for diagnostics, management, AV targets, VersaPHY initiator or targets...), to pick up their GUID to use it as GUID of an SBP2 target instance, and of course for informational purposes. * tag 'firewire-updates' of git://git.kernel.org/pub/scm/linux/kernel/git/ieee1394/linux1394: firewire: core: document is_local sysfs attribute firewire: core: add is_local sysfs device attribute firewire: ohci: initialize multiChanMode bits after reset firewire: core: fix multichannel IR with buffers larger than 2 GB firewire: ohci: sanity-check MMIO resource firewire: ohci: lazy bus time initialization firewire: core: allocate the low memory region firewire: core: make address handler length 64 bits
