[PATCH 10/12] selftests/hid: tablets: convert the primary button tests

From: Benjamin Tissoires
Date: Wed Nov 29 2023 - 10:56:47 EST


We get more descriptive in what we are doing, and also get more
information of what is actually being tested. Instead of having a non
exhaustive button changes that are semi-randomly done, we can describe
all the states we want to test.
