Subject: [PATCH 05/12] selftests/hid: tablets: move the transitions to
PenState
Those transitions have nothing to do with `Pen`, so migrate them to
`PenState`.
The hidden agenda is to remove `Pen` and integrate it into `PenDigitizer`
so that we can tweak the events in each state to emulate firmware bugs.
