Wrong format for a multi-line comment. It should look like this:
/*
* Blah, blah, blah
* blah, blah, blah
*/
Also, the reference to fsg is obsolete; the File-backed Storage Gadget
is no longer in the kernel. You might as well leave the comment out
entirely.

This test shouldn't be here. The UDC drivers don't do it, but they
probably do check the req->complete isn't NULL when the request is
submitted. In any case, if req->complete is NULL then we want to know
about it because it is a bug. It should not be covered up silently.
