Subject: [PATCH] driver core: remove unheeded warning about driver methods

This patch (as1263) removes a warning which has been present for so
long, and consistently ignored, that it obviously is not doing any
good.  It gets triggered on pretty much every boot by the SCSI disk
and cdrom drivers.  Evidently nobody cares.
