I'm not aware of a place to store such ODD specific information when probing the device. I'm currently storing the loading mech type in structure zpodd, which gets created after the corresponding SCSI device gets created in ata_scsi_scan_host, so at the probe time, the zpodd structure does not exist yet. And the reason I create the zpodd sturcture this late is that, it is only created when the ODD together the platform is ZPODD capable, and to find out if this platform is ZPODD capbale, ACPI binding has to occur first, and ACPI binding happens when SCSI device is added to the device tree.
