Subject: [Patch 5/5] dt: unittest: breadcrumbs to reduce pain of future maintainers

From: Frank Rowand <frank.rowand@...ymobile.com>

Fix warnings pointed out by checkpatch.

Checkpatch warns: externs should be avoided in .c files

Reducing pain for future maintainers - adding a comment so that anyone trying
to find where the extern data is created will be able to find it.
(grep will not find that location)
