There were 63 instances of counting semaphores used for each hpsb_host.
All of them are now replaced by a single wait_queue.
After this and patch "ieee1394: dv1394: sem2mutex conversion", the following semaphores remain in the ieee1394 subsystem:
highlevel.c: hl_drivers_sem (RW semaphore)
nodemgr.c: subsys.rwsem (driver core's RW semaphores)
raw1394.c: fi->complete_sem (completion semaphore)
