Subject[PATCH v5 09/13] ALSA: hda/ca0132: add the ability to set src_id on scp commands
Date
This patch adds the ability to change the src_id on scp commands, which
is used in the dsp setup of the Recon3Di and the Sound Blaster Z. It
also makes sure to maintain backwards compatibility with the older
dspio_set_uint_param function, and sets it's src to the default 0x20.
