Stefan Richter 45289bf6ac [PATCH] ieee1394: raw1394: remove redundant counting semaphore 
An already existing wait queue replaces raw1394's complete_sem which was
maintained in parallel to the wait queue.  The role of the semaphore's
counter is taken over by a direct check of what was really counted:  The
presence of items in the list of completed requests.

Notes:

 - raw1394_release() sleeps uninterruptibly until all requests were
   completed.  This is the same behaviour as before the patch.

 - The macros wait_event and wait_event_interruptible are called with a
   condition argument which has a side effect, i.e. manipulation of the
   requests list.  This side effect happens only if the condition is
   true.  The patch relies on the fact that wait_event[_interruptible]
   does not evaluate the condition again after it became true.

 - The diffstat looks unfavorable with respect to added lines of code.
   However 19 of them are comments, and some are due to separation of
   existing code blocks into two small helper functions.
