My mistake, this actually needs to be submitted to 3.2.x stable.

** Description changed:

  SRU Justification:
  
      Impact: Users of the 3.5 kernel may not be able to use their usbaudio devices.
      Fix: commit 61ac51301e6c6d4ed977d7674ce2b8e713619a9b upstream. This is already applied to 3.2 and 3.8 kernels.
      Testcase: Build with the fix, attach affected usbaudio devices. See if those devices work after the patch.

  For some usbaudio devices, an unexpected type can cause parse_audio_unit() to fail.
  This results in a message like the following:
  
  [544717.685926] usb 1-1.5: new high-speed USB device number 14 using ehci_hcd
  [544717.779149] usb 1-1.5: New USB device found, idVendor=1235, idProduct=8014

  [544717.833568] usbaudio: unit 52: unexpected type 0x09
  
  The commit 61ac51301e6c6d4ed977d7674ce2b8e713619a9b, allows for this
  type to also be handled, allowing the usbaudio device to operate.
  
  This was fixed in v3.9-rc4 and beyond; therefore precise/quantal and
  raring are affected. However it looks like the patch landed in stable
- for 3.2.x and 3.8.x.
+ for 3.8.x.
