Drivers 'sd' & 'sr' need updating: please use bus_type methods...

I turned on the option to flag deprecated code, and these two popped up:
Driver 'sd' needs updating - please use bus_type methods Driver 'sr' needs updating - please use bus_type methods

I'm assuming these are referring to the SCSI devices?

I'm assuming they are already "known about"?

Just checking...
