See http://www.infradead.org/rpr.html Precedence: bulk List-ID: X-Mailing-List: linux-kernel@vger.kernel.org The swim driver (unlike various other floppy drivers) doesn't have magic device nodes for certain modes, and already registers a gendisk for each of the floppies supported by a device. Thus the region registered is a no-op and can be removed.
