File src/drivers/wifi/generic/acpi.c:

PS19, Line 515: memcpy(dsm, &sar_limits.dsm, sizeof(struct dsm_profile));
one more nit: instead of using memcpy, when the dest and src are the same type, you can have C help you out a little and just do:
`*dsm = sar_limits.dsm`

PS19, Line 537: dev = dev->link_list->children;
              : 	const struct drivers_wifi_generic_config *config = dev->chip_info;
              : 	bool is_cnvi_ddr_rfim_enabled;
              : 
              : 	is_cnvi_ddr_rfim_enabled = config->enable_cnvi_ddr_rfim;
one more thing, you can reuse the function from the previous patch, e.g..

```
const struct device *generic = dev->link_list->children;
if (generic && generic->path.type == DEVICE_PATH_GENERIC)
    is_cnvi_ddr_rfim_enabled = wifi_generic_cnvi_ddr_rfim_enabled(generic);
```
