firewire-core and raw1394 do not actually require the BKL, they only
miss to declare their files as not seekable.  I will post patches which
change these accordingly.

My guess is that there is nothing to seek in dv1394, video1394, and
firedtv either.

Needless to say, there may be other character device file interfaces
which cannot be seeked but don't admit it yet.
