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

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

* tag 'firewire-updates' of git://git.kernel.org/pub/scm/linux/kernel/git/ieee1394/linux1394:
  firewire: sbp2: document the absence of alignment requirements
  firewire: sbp2: remove superfluous blk_queue_max_segment_size() call
  firewire: sbp2: use scsi_dma_(un)map
  firewire: sbp2: give correct DMA device to scsi framework
  firewire: core: fw_device_refresh(): clean up error handling
  firewire: core: log config rom reading errors
  firewire: core: log error in case of failed bus manager lock
  firewire: move rcode_string() to core
  firewire: core: improve reread_config_rom() interface
  firewire: core: wait for inaccessible devices after bus reset
  firewire: ohci: omit spinlock IRQ flags where possible
  firewire: ohci: correct signedness of a local variable
  firewire: core: fix DMA mapping direction
  firewire: use module_pci_driver
