I can't think of any such trivial fix. My submitted code includes a
whole new driver, thinkpad_ec, just to get the (fully documented!) EC
protocl right. You could strip a few code paths which hdaps doesn't
invoke, but it's hard to see how you can get away with much less
except by making unwarranted assumptions about the hardware and its
timing characteristics.
