of_find_device_by_node() returns the ASRC platform device with a
reference taken, but asrc_pdev is only used during probe to set up the
DPCM DAI links and is never released. The shared exit path already drops
the CPU device reference, so release the ASRC one there too, covering
both the error paths and the successful registration path.

ASRC support")
