[PATCH 05/11] selftests: hid: import hid-tools hid-mouse tests

From: Benjamin Tissoires
Date: Fri Feb 17 2023 - 11:20:48 EST


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.
