Disregard the > monthly warming reports? At least for SCSI, the warning is wrong .. the drivers are properly converted. The issue that triggers the warning is that we use the bus_type power management methods to receive the notifies in the mid-layer (where we do mid-layer specific stuff) then we notify the drivers through the driver power management methods. A solution would be to duplicate the power management methods in the scsi_driver structure, but this is a complete waste of space since the generic driver ones aren't going away (at least according to Kay and Greg). I still think the best thing to do is just to turn off this spurious warning.
