[PATCH 0/2] ALSA: usb-audio: Insertion Control for BADD Adaptors.

This patchset adds support for the Insertion Control for BADD devices (subset of UAC3).

This control is only pressent in the HEADSET ADAPTER BADD profile. The USB interrupt pipe
shall be present for this profile so the status pipe creation should also happen for BADD

Also, the bi-directional type codes have been defined so they can be used as inferred values
for the Input and Output terminals for this adapter profile.

Based on tag: next-20180612

Jorge Sanjuan (2):
  ALSA: usb-audio: Add bi-directional terminal types.
  ALSA: usb-audio: UAC3. Add insertion control for BADD.
