It is quite likely that the number of U-Boot-specific tests in checkpatch.pl will increase over time. We should have tests for these to avoid undefined behaviour and bugs being introduced, which might cause people to ignore the warnings. Add a simple new class that can generate a patch with a single-line addition in it. Use that to add a test for one of the checkpatch checks.
