Sergey Larin 6b1072a789 samsung-i927: Kernel updates (!217) 
- Use separated patches
- Use new panel driver (with backlight support)
- Battery fixes
- Fix compass (AK8975) (not tested, only probing works, but sometimes
  doesn't - says "Unexpected device" - need to investigate that)
- Touchkey is working + LED
- Keyboard backlight + HALL for slideout detection
