Merge tag 'firewire-updates' of git://git.kernel.org/pub/scm/linux/kernel/git/ieee1394/linux1394

Pull firewire updates from Stefan Richter:
 "Make struct ieee1394_device_id.driver_data actually avaliable to 1394
  protocol drivers.  This is especially useful to 1394 audio drivers for
  model-specific parameters and methods"

* tag 'firewire-updates' of git://git.kernel.org/pub/scm/linux/kernel/git/ieee1394/linux1394:
  firewire: remove support of fw_driver.driver.probe and .remove methods
  firewire: introduce fw_driver.probe and .remove methods
