From c8547119ce54ef6d3c0685ef3837514fa6e11d28 Mon Sep 17 00:00:00 2001 From: Frank Rowand Date: Sat, 14 Mar 2015 00:04:24 -0700 Subject: [PATCH] of/unittest: breadcrumbs to reduce pain of future maintainers 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.
