ALSA: isight: fix isight_pcm_abort() crashes Fix crashes in isight_pcm_abort() that happen when the driver tries to access isight->pcm->runtime which does not exist when the device is not open.

ALSA: isight: adjust for new queueing API Since commit 13882a82ee16 (optimize iso queueing by setting wake only after the last packet), drivers are required to call fw_iso_context_queue_flush() after queueing a batch of packets. The missing call would have an effect only if the controller queue underruns, but then the DMA would stop completely.

firewire: move fw_device reference counting from drivers to core 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: Stefan Richter <stefanr@s5r6.in-berlin.de>

ALSA: isight: fix locking Lockdep complains about conflicts between isight->mutex, ALSA's register_mutex, mm->mmap_sem, and pcm->open_mutex. This can be fixed by moving the calls to isight_pcm_abort(), snd_card_disconnect(), and fw_iso_resources_update() out of isight->mutex. These functions are designed to be called asynchronously; the mutex needs to protect only the device streaming state modified by isight_start/stop_streaming().

ALSA: isight: fix hang when unplugging a running device 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: Clemens Ladisch <clemens@ladisch.de> Signed-off-by: Takashi Iwai <tiwai@suse.de>
