[PATCH 1/2] of/unittest: Show broken behaviour in the platform bus

From: Grant Likely
Date: Sun Jun 07 2015 - 13:01:30 EST


Add a single resource to the test bus device to exercise the platform
bus code a little more. This isn't strictly a devicetree test, but it is
a corner case that the devicetree runs into. Until we've got platform
device unittests, it can live here. It doesn't need to be an explicit
text because the kernel will oops when it is wrong.
