I'm fine with the changes, but they need to be submitted with the other changes
as this one change cannot compile independently in my tree.
Finn, please work with whomever is pulling the series to include this in their
pull request.

Sure. Those results were just confirmation that this patch series doesn't
affect input events read directly from
/dev/input/by-path/platform-thinkpad_acpi-event
given the the hotkey_source_mask settings discussed in this thread.

After I told him which exact bitmask to use on a T43 to test
hotkey_source_mask, his test results can be summarized as "I could see
no difference in behavior", which is *exactly* what I expected to
happen.
If anything went wrong with the thinkpad-acpi NVRAM code, you'd notice a
very large change in behavior (typical: hotkeys don't work, less
typical: random hotkey keypresses, hotkey press bursts, low responsivity
of hotkeys).

Perfect, thanks for the update so we have it recorded here on the list.
