From: Kamil Lulko kamilx.lulko@intel.com
cAVS modules do not require Type and Length header within the set_module_params IPC. This is also true for Vendor modules. The userspace (like tinymix) always appends this header to TLV controls which are used for set_module_params. Simply assume this header is always present in the payload and omit it from the IPC.
