IdeaPad Slidebar Driver Comes In For Linux 3.12
Lenovo Y-Series IdeaPad laptops have a touch panel that has a navigation slidebar as described in this bug report. An ideapad-slidebar driver was developed this summer (the original code) for IdeaPad laptops and was written through reverse-engineering Lenovo's SlideNav software for Windows. With the 3.12 kernel, this driver is merged.
The other input driver changes for the Linux 3.12 kernel are mostly scattered minor improvements.
