Log errors are the most widely used mechanism for reporting issues in
the kernel. When an error is logged using the device helpers, eg
dev_err(), it gets metadata attached that identifies the subsystem and
device where the message is coming from. Introduce a new test that makes
use of that metadata to report which devices logged errors (or more
critical messages).
