3.16-stable review patch. If anyone has any objections, please let me know.
------------------ From: Andrzej Pietrasiewicz <[email protected]> commit 4546527350c3c508554dff53e9086e9d3de0b97b upstream. f->os_desc_table[0].if_id is zero by default. If the actual id happens to be different then no Feature Descriptors will be returned to the host for this interface, so assign if_id as soon as it is known.
