[PATCH v2 0/2] ALSA: Fix usb-audio races

Show all headers | View raw

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.
