Subject[PATCH 3.18 21/83] Input: xpad - add rumble support for Xbox One controller
Date
3.18-stable review patch.  If anyone has any objections, please let me know.

------------------

[ Upstream commit 0604949ce3b9a59cff419daf706272620a9a0df0 ]

This adds rumble support for Xbox One controller by sending continuous
rumble command. Trigger button rumbling is not yet implemented.
