Well, I didn't specify exactly /which/ coming week, did I?

Right now I finished addressing a few of those "potential submission
hurdles" --- I rewrote all accesses of on-the-wire data which used
bitfields in struct types to use open-coded bit shifts and bit masks
instead.  Furthermore I removed some unused declarations and

I briefly tested these somewhat intrusive changes with a FireDTV-C/CI
and a FireDTV-T/CI, both without CA module.  But I would appreciate it
if somebody else looks at these changes as well to catch possible

Pushed out to linux1394-2.6.git, will also update my quilt series soon:

Stefan Richter (5):
      firedtv: avc: remove bitfields from FCP frame types
      firedtv: avc: header file cleanup
      firedtv: avc: remove bitfields from DSD command operands
      firedtv: avc: remove bitfields from read descriptor response operands
      firedtv: avc, ci: remove unused constants

What I still want to do before I post everything at LKML is less
ambitious:  Some whitespace and comment style changes, remove a kernel
version compatibility macro, use dev_printk, remove some pointer type
casts, collapse all header files into a single one.

So that should go swifter than the bitfield conversions.  Also, it's
quiet at the drivers/firewire and drivers/ieee1394 fronts at the moment,
giving me some room for firedtv work.
