ide-{floppy,tape}: cleanup ide*_end_request()
* ide*_end_request() is only called with uptodate == 0 or uptodate == 1 so cleanup it accordingly. * Inline ide*_end_request() content at call sites so the only user left is ->end_request method. * ->end_request is now used only for private driver requests so remove handling of other requests from ide*_end_request(). There should be no functional changes caused by this patch. Acked-by: Borislav Petkov <petkovbb@gmail.com> Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
