Subject: [GIT PULL] ieee1394 update

Linus, please pull from the for-linus branch at

    git://git.kernel.org/pub/scm/linux/kernel/git/ieee1394/linux1394-2.6.git for-linus

to receive a regression fix for ieee1394 and a trivial bit for firewire.

    ieee1394: fix NULL pointer dereference in sysfs access
    
    Regression since "ieee1394: prevent device binding of raw1394,
    video1394, dv1394", commit d2ace29fa44589da51fedc06a67b3f05301f3bfd:
    $ cat /sys/bus/ieee1394/drivers/raw1394/device_ids
    triggers a NULL pointer dereference in fw_show_drv_device_ids.
