Remove the Result typedef
Many of our functions do not return a Result<_, Error>, but for example a Result<_, (Device, Error)>. We only use the typedef in one function, but it makes the other functions more complicated as we have to use result::Result (if crate::Result is imported). Therefore, this patch removes the typedef. Applications or libraries can still redefine it if they want to.
