This driver adds support for slidebars found on some Lenovo IdeaPad laptops (the slidebars work with SlideNav/Desktop Navigator under Windows). Fixes: https://bugzilla.kernel.org/show_bug.cgi?id=16004 Registers 'IdeaPad Slidebar' input device and /sys/devices/platform/ideapad_slidebar/slidebar_mode for switching slidebar's modes. Now works on: IdeaPad Y550, Y550P. May work on (testing and adding new models is needed): Ideapad Y560, Y460, Y450, Y650, and, probably, some others.
