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). Signed-off-by: Nícolas F. R. A.
