Adding more debug code shows that it's the test on evbit [1] in
input_match_device_id() that fails.
Looking at your input_test_match_device_id(), I think you expect
the checks for the various bitmaps to be gated by
"if (id->flags & INPUT_DEVICE_ID_MATCH_EVBIT)", like is done for the
other checks?

when I'm talking to journalists I just say "programmer" or something like that.
