Remove a field that is not used at all. This remained from
earlier tests, but the current driver has decided not to handle
iris notifications.Signed-off-by: Clemens Ladisch

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.Signed-off-by: Clemens Ladisch

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().Signed-off-by: Clemens Ladisch

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.

After handling a received packet, we want to resubmit the same packet,

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. Introduce a new field pcm_active to track this state.Signed-off-by: Clemens Ladisch
