    Pull IEEE 1394 (FireWire) subsystem updates from Stefan Richter:
    
     - Fix mismatch between DMA mapping direction (was wrong) and DMA
       synchronization direction (was correct) of isochronous reception
       buffers of userspace drivers if vma-mapped for R/W access.  For
       example, libdc1394 was affected.
    
     - more consistent retry stategy in device discovery/ rediscovery, and
       improved failure diagnostics
    
     - various small cleanups, e.g. use SCSI layer's DMA mapping API in
       firewire-sbp2
