Do we need to propagate the error code here in case the USB PHY for some
reason doesn't support the given current? Or is it guaranteed that we
always do support whatever is passed in here?
Regardless of whether we support it or not, it might still be useful to
add proper handling, if for nothing else but to set a good example.

Will update accordingly, propagate the return the code to caller.
