Move the ASP register patches to a separate struct and apply this from the ASP DAI probe() function so that the registers are only patched if the DAI is part of a DAI link. Some systems use the ASP as a special-purpose interconnect and on these systems the ASP registers are configured by a third party (the firmware, the BIOS, or another device using the amp's secondary host control interface). If the machine driver does not hook up the ASP DAI then the ASP registers must be omitted from the patch to prevent overwriting the third party configuration. If the machine driver includes the ASP DAI in a DAI link, this implies that the machine driver and higher components (such as alsa-ucm) are taking ownership of the ASP. In this case the ASP registers are patched to known defaults and the machine driver should configure the ASP.
