Make this explicit to prevent the following section mismatch warnings WARNING: modpost: drivers/scsi/sun3_scsi: section mismatch in reference: sun3_scsi_driver+0x4 (section: .data) -> sun3_scsi_remove (section: .exit.text) WARNING: modpost: drivers/scsi/sun3_scsi_vme: section mismatch in reference: sun3_scsi_driver+0x4 (section: .data) -> sun3_scsi_remove (section: .exit.text) that trigger on a Sun 3 allmodconfig build.
