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
