  * d/p/0001-ucm-handle-correctly-Linked-configuration.patch
    - If the sound card is Linked in the ucm, don't return error

      audio can't work. (LP: #1901922)

  * d/p/0001-ucm-add-a-check-for-the-empty-configuration.patch
  - Fix the failure on init the HDA-Intel sound card, because there
    is no init mixer values in the ucm, the alsa-lib should return
    error and then let alsautils init this sound card in the legacy
    HDA way. (LP: #1897934)
