    SCSI folks, the background is that we have moved the dev_*() printk
    macros to external functions, so that the prefixing printf strings
    don't get emitting at every call site.

    As a consequence, dev_*() calls that try to use an empty string as the
    printf format emit a warning from gcc since an empty constant string
    is not a valid printf format.

    That's what this change is all about.
