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.

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.

fw_unit device drivers invariably need to talk to the fw_unit's parent (an fw_device) and grandparent (an fw_card). firewire-core already maintains an fw_card reference for the entire lifetime of an fw_device. Likewise, let firewire-core maintain an fw_device reference for the entire lifetime of an fw_unit so that fw_unit drivers don't have to. Signed-off-by: NStefan Richter <stefanr@s5r6.in-berlin.de>

There is a lock inversion between fwspk->mutex and pcm->open_mutex reported by lockdep when fwspk_hw_free is called. Fixed by copying the fix from the same former issue in the isight sound driver (commit f3f7c183 "ALSA: isight: fix locking").

Since commit f2b3614c (Don't check DMA time-out too shortly), drivers need no longer restrict their PCM period length to be shorter than 10 seconds. Signed-off-by: NClemens Ladisch <clemens@ladisch.de> Signed-off-by: NTakashi Iwai <tiwai@suse.de>

When aborting a PCM stream, the xrun is signaled only if the stream is running. When disconnecting a PCM stream, calling snd_card_disconnect() too early would change the stream into a non-running state and thus prevent the xrun from being noticed by user space. To prevent this, move the snd_card_disconnect() call after the xrun. Signed-off-by: NClemens Ladisch <clemens@ladisch.de> Signed-off-by: NTakashi Iwai <tiwai@suse.de>

Add an AMDTP stream error state that occurs when we fail to queue another packet. In this case, the stream is stopped, and the error can be reported when the application tries to restart the PCM stream.
