I believe this warning gets lost in this patch.

To get it back, let's make 'copy_virtio_drivers' returns a true/false
indication ('true' meaning that at least some drivers were copied),
and the caller code in 'install_virtio_drivers' should check this, and
either do the code above, or continue with the code below.

Don't need parentheses around if-conditions.

The rest of the patch looks good with these two changes.

Rich.
