[git pull] FireWire updates post v3.4

[Stefan Richter]

Linus,

please pull from the tag "firewire-updates" at

    git://git.kernel.org/pub/scm/linux/kernel/git/ieee1394/linux1394.git firewire-updates

to receive the following IEEE 1394 (FireWire) subsystem updates:

  - 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

The last few commits happened rather late for this pull request but I feel comfortable
with them.  ALSA firewire-lib changes were written by Clemens, hence are implicitly ACKed.

Axel Lin (1):
      firewire: use module_pci_driver

Clemens Ladisch (10):
      firewire: core: wait for inaccessible devices after bus reset
      firewire: core: improve reread_config_rom() interface
      firewire: move rcode_string() to core
      firewire: core: log error in case of failed bus manager lock
      firewire: core: log config rom reading errors
      firewire: core: fw_device_refresh(): clean up error handling
      firewire: sbp2: give correct DMA device to scsi framework
      firewire: sbp2: use scsi_dma_(un)map
      firewire: sbp2: remove superfluous blk_queue_max_segment_size() call
      firewire: sbp2: document the absence of alignment requirements

Stefan Richter (4):
      firewire: core: fix DMA mapping direction
      firewire: ohci: correct signedness of a local variable
      firewire: ohci: omit spinlock IRQ flags where possible
      Merge tag 'v3.4' with SCSI updates, needed for subsequent firewire-sbp2 changes
