The function returns val as int instead of u32. While this shouldn't be a
problem in this case, maybe there should be an additional check just to be
sure?

As far as I can tell coverity is not reporting any issue around it.
And when I look at internal of that function in firmware this function
in case of success returns only 0 or 1 that's why I don't think we need
to do anything with it.

Thanks,
Michal
