Pull firewire updates from Stefan Richter:
 "Make struct ieee1394_device_id.driver_data actually avaliable to 1394
  protocol drivers.  This is especially useful to 1394 audio drivers for
  model-specific parameters and methods"

ALSA: firewire: fix error return code in scs_probe()

2013-06-18T14:11:57+00:00

Fix to return -ENOMEM in the kmalloc() error handling
case instead of 0, as done elsewhere in this function.

firewire: introduce fw_driver.probe and .remove methods

2013-06-09T16:15:00+00:00

FireWire upper layer drivers are converted from generic
    struct driver.probe() and .remove()
to bus-specific
    struct fw_driver.probe() and .remove().

The new .probe() adds a const struct ieee1394_device_id *id argument,
indicating the entry in the driver's device identifiers table which
matched the fw_unit to be probed.  This new argument is used by the
snd-firewire-speakers driver to look up device-specific parameters and
methods.  There is at least one other FireWire audio driver currently in
development in which this will be useful too.

The new .remove() drops the unused error return code.

Although all in-tree drivers are being converted to the new methods,
support for the old methods is left in place in this commit.  This
allows public developer trees to merge this commit and then move to the
new fw_driver methods.

ALSA: firewire-speakers: remove __dev* attributes

2012-12-07T06:29:30+00:00

CONFIG_HOTPLUG is going away as an option.  As result the __dev*
markings will be going away.

Remove use of __devinit, __devexit_p, __devinitdata, __devinitconst,
and __devexit.

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

ALSA: firewire-lib: optimize packet flushing

2012-05-14T08:43:43+00:00

Trying to flush completed packets is pointless when the pointer
callback was called from the packet completion callback; avoid it.

ALSA: firewire-lib: flush completed packets when reading PCM position

2012-05-14T08:43:36+00:00

By flushing all completed but not yet reported packets before reading
the PCM hardware position, the granularity of the pointer is improved
from the interrupt interval to the packet size.

ALSA: firewire-lib: taskletize the snd_pcm_period_elapsed() call

2012-05-14T08:43:30+00:00

The following patch might introduce this call chain:
  PCM .pointer callback
  + fw_iso_context_flush_completions
    + packet callback
      + snd_pcm_period_elapsed
        + PCM .pointer callback
Recursive calls to the pointer callback are not possible due to the PCM
group locking, so avoid this by moving the period notification into
a separate tasklet.
