Subject[PATCH v2 0/2] ALSA: Fix usb-audio races
Date
Many thanks to Takashi Iwai & Sakamoto for their awesome feedback.

Changes since v1:
* Rebased my fix on top of tiwai's revert and integrated the changes
from the original fix into this.
* Dropped the stop_endpoints() call inside snd_usb_pcm_prepare() and
kept the previously existing snd_usb_endpoint_sync_pending_stop() call.
* Retained the deactivate_urbs() call in snd_usb_pcm_prepare(), I only
removed the can_sleep logic.
* Split the EP_FLAG_RUNNING check in a separate commit to keep the log
clean since this is not part of the race fix.
