@veskola I managed to apply the patch. It was a problem with the Yocto build (you can see this post).
@smagrian I applied the patch (created using the entire file), but the result is the same. The only difference is that when waking up from sleep I get 3 error messages (Unable to fetch data, error: -13) instead of 5 (as shown in my first post).
