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
