PS18, Line 606: if (*is_cnviDdrRfim_enabled) {
              : 		dsm_ids[dsm_count].uuid = ACPI_DSM_RFIM_WIFI_UUID;
              : 		dsm_ids[dsm_count].callbacks = &wifi_dsm2_callbacks[0];
              : 		dsm_ids[dsm_count].count = ARRAY_SIZE(wifi_dsm2_callbacks);
              : 		dsm_ids[dsm_count].arg = (void *)is_cnviDdrRfim_enabled;
              : 		dsm_count++;
              : 	}
Also taking another look at this, would we ever add the DSM subfunction for CNVi DDR RFIM enabled" that would return 0, not enabled? This code effectively would never do that, because the if(is_cnvi_ddr_rfim_enabled) skips writing out the DSM sub function is false, so in theory wifi_dsm_ddrrfim_func3_cb could just be

acpigen_write_return_integer(1);

No big deal though
