I have no objection to the above changes relevant to firewire subsystem.

Acked-by: Takashi Sakamoto <o-takashi at sakamocchi.jp>

Consequently, unit drivers just include include/linux/firewire.h to refer 
to 'struct ieee1394_device_id'. After merging the changes, I'll post more
patches to modify the following unit drivers, since they are left from the
patchset.

* drivers/media/firewire/firedtv.h
* sound/firewire/bebob/bebob.h
* sound/firewire/dice/dice.h
* sound/firewire/digi00x/digi00x.h
* sound/firewire/fireface/ff.h
* sound/firewire/fireworks/fireworks.h
* sound/firewire/motu/motu.h
* sound/firewire/oxfw/oxfw.h
* sound/firewire/tascam/tascam.h

By the way, the changes touch so many files. If it takes more time to
apply, I think it better to make steps to modify across several kernel
generation. For example, getting rid of direct reference of
mod_devicetable.h from drivers at first (in the case of firewire
subsystem, for 'Replace <linux/mod_devicetable.h> by more specific
<linux/device-id/*.h> (headers))', then adding these per-subsystem
headers and applying relevant changes.

Of course, I don't mind to apply the v3 patchset as is in upstream.


Thanks
