Cover letter [Patch 0/5] dt: unittest: fix breakage and warnings

Running checkpatch on early versions of my patchset to fix the devicetree make dependency issues exposed a large number of warnings, including some that are actual bugs. http://lkml.iu.edu/hypermail/linux/kernel/1503.1/03335.html

These patches fix those bugs, and another bug exposed by fixing those bugs. As a result, the number of tests completed increased from 102 to 107.

Since I was already poking around, I fixed a few classes of checkpatch warnings.

There are still plenty of warnings, but the noise is greatly reduced and future checkpatch warnings that are problems should stand out more clearly.
