If a driver sets blk_queue_prep_rq() it should clean up itself
and not rely on the bus callbacks to handle this. This removes
the need to hook into bus->remove() as these should not be used
at the same time as driver->remove().

Here it is declared void
but

Here it is returning int.

My FC10 compiler does not like that:
drivers/scsi/scsi_lib.c:1415: error: conflicting types for 'scsi_reset_prep_fn'
include/scsi/scsi_driver.h:35: error: previous declaration of 'scsi_reset_prep_fn' was here

#endif /* _SCSI_SCSI_DRIVER_H */

I fixed it to be void, will test later

Argl. You are correct. New patch attached.

Cheers,

Hannes
