Introduce a new kselftest to detect devices that were declared in the Devicetree, and are expected to be probed by a driver, but weren't. The test uses two lists: a list of compatibles that can match a Devicetree device to a driver, and a list of compatibles that should be ignored. The first is automatically generated by the dt-extract-compatibles script, and is run as part of building this test. The list of compatibles to ignore is a hand-crafted list to capture the few exceptions of compatibles that are expected to match a driver but not be bound to it. Signed-off-by: Nícolas F. R. A.
