All the HDAudio codec handling is completely specific to Linux and
completely dependency on GPL2.0 code, specifically the snd_hdac_
library.
There was no intention to have a dual-license for this code, this was
an oversight that needs to be corrected. Update the SPDX and
EXPORT_SYMBOL information, no functionality change otherwise.
