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.

Anyways:
