3.16-stable review patch. If anyone has any objections, please let me know.
------------------ From: Hans de Goede <[email protected]> commit 43508be512661c905d0320ee73e0b65ef36d2459 upstream. So that an user who wants to use uas can see why he is not getting uas. Also move the check down so that we don't warn if there are other reasons why uas cannot work.
