For the three introduced structures:
- camss_params_color_correct is the same as the one you supplied
- camss_params_wb_gain has three extra offset appended (post gain), as
supported by the hardware. But maybe the signed offsets you introduced
were supposed to support both pre/post based on the sign?
- camss_params_chroma_enhan is newly introduced here
