109 to be called by the USB offload driver residing in USB SND.
122 audio device removal. This is intended to be called by the USB offload
160 - ``dev``: USB device to look up offload path mapping
163 - ``direction``: direction to fetch offload routing information
165 - ``route``: mapping of sound card and pcm indexes for the offload path. This is
172 offload for the device. ``route`` may be a pointer to a kcontrol value output array,

398 the mapped offload card and pcm device indexes for the specific USB device:
400 ``USB Offload Playback Card Route PCM#*``
402 ``USB Offload Playback PCM Route PCM#*``
407 - ``USB Offload Playback Card Route PCM#`` **(R)**: Returns the ASoC platform sound
408 card index for a mapped offload path. The output **"0"** (card index) signifies
409 that there is an available offload path for the USB SND device through card#0.
410 If **"-1"** is seen, then no offload path is available for the USB SND device.
412 its expected to derive the current status of offload based on the output value
415 - ``USB Offload Playback PCM Route PCM#`` **(R)**: Returns the ASoC platform sound
416 PCM device index for a mapped offload path. The output **"1"** (PCM device index)
417 signifies that there is an available offload path for the USB SND device through
418 PCM device#0. If **"-1"** is seen, then no offload path is available for the USB\
420 system, and its expected to derive the current status of offload based on the
