IEEE 1394 (FireWire) subsystem updates post v3.3:

Browse source 
- Some SBP-2 initiator fixes, side product from ongoing work on a target.
   - Reintroduction of an isochronous I/O feature of the older ieee1394 driver
     stack (flush buffer completions); it was evidently rarely used but not
     actually unused.  Matching libraw1394 code is already available.
   - Be sure to prefix all kernel log messages with device name or card name,
     and other logging related cleanups.
   - Misc other small cleanups, among them a small API change that affects
     sound/firewire/ too.

Merge tag 'firewire-updates' of git://git.kernel.org/pub/scm/linux/kernel/git/ieee1394/linux1394

Pull IEEE 1394 (FireWire) subsystem updates post v3.3 from Stefan Richter:

 - Some SBP-2 initiator fixes, side product from ongoing work on a target.

 - Reintroduction of an isochronous I/O feature of the older ieee1394 driver
   stack (flush buffer completions); it was evidently rarely used but not
   actually unused.  Matching libraw1394 code is already available.

 - Be sure to prefix all kernel log messages with device name or card name,
   and other logging related cleanups.

 - Misc other small cleanups, among them a small API change that affects
   sound/firewire/ too. Clemens Ladisch is aware of it.
