[Roxana Nicolescu]

https://bugs.launchpad.net/bugs/2076402

SRU Justification:

[Impact]
Coming from the author of the ALSA scarlett2 driver.
Users have been reporting issues where the driver sometimes fails to
initialize or fails later when being used.

  source

    notification
They are clean cherry-picks.
