Sorry, but don't quite understand this.
We have ACPI bindings for scsi devices, isn't that for us to use ACPI
when needed in scsi?
BTW, if sr_suspend should be generic, that would suggest I shouldn't
write any ZPODD related code there, right? Any suggestion where these
code should go then?
Thanks,
Aaron
