Introduce CONFIG guards for the mux functions so that drivers can include the header file and not run into compilation errors on systems which don't have CONFIG_TYPEC enabled. When CONFIG_TYPEC is not enabled, the Type C mux functions will be stub versions of the original calls. Reported-by: kernel test robot Reviewed-by: Nícolas F. R. A.
