First, I am quilty here. I've let INPUT_PROP_ACCELEROMETER slip through my tree without Dmitry's Ack, which is what I normally require for everything touching input.h. Mea culpa maxima, I missed it, sorry for that. This makes sense to me though. So Acked-by: Jiri Kosina <jkosina@xxxxxxx> but let's see what Dmitry has to say. Good thing is that this went only into 4.0-rc1, so if the whole INPUT_PROP_ACCELEROMETER turns out to be absolute no-go for some reason, we can still revert it.
