These tests have been developed in the hid-tools[0] tree for a while. Now that we have a proper selftests/hid kernel entry and that the tests are more reliable, it is time to directly include those in the kernel tree. I haven't imported all of hid-tools, the python module, but only the tests related to the kernel. We can rely on pip to fetch the latest hid-tools release, and then run the tests directly from the tree. This should now be easier to request tests when something is not behaving properly in the HID subsystem.
