[PATCH 05/12] selftests/hid: tablets: move the transitions to PenState

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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.
