Some mouses have a switch on their wheel, allowing to switch between ratchet or free wheel mode. Add support for it.
I understand the want to support it because it's there but what do you expect this to be used for? tbh, I wouldn't know what to do with this information, short of displaying some OSD to inform the user. Which is rather superfluous since the physical change will feel obvious anyway. A Documentation/input/event-codes.txt hunk would be welcomed here too btw. Cheers, Peter
