John Hubbard ffca476a0a rapidio: fix an error in get_user_pages_fast() error handling ... In the case of get_user_pages_fast() returning fewer pages than requested, rio_dma_transfer() does not quite do the right thing. It attempts to release all the pages that were requested, rather than just the pages that were pinned. Fix the error handling so that only the pages that were successfully pinned are released.
