I got a little build error about some unresolved symbols in the module
while compiling:

ERROR: "sparse_keymap_setup" [drivers/platform/x86/ideapad-laptop.ko] undefined!
ERROR: "sparse_keymap_free" [drivers/platform/x86/ideapad-laptop.ko] undefined!
ERROR: "sparse_keymap_report_event" [drivers/platform/x86/ideapad-laptop.ko] undefined!

You can get it to go away by setting CONFIG_INPUT_SPARSEKMAP=m or =y
in .config. But, I think your patches need this:

diff --git a/drivers/platform/x86/Kconfig b/drivers/platform/x86/Kconfig
index faec777..879d266 100644

This is a driver for the rfkill switches on Lenovo IdeaPad netbooks.
