Hotkey enabled by this patch:
Fn+F3: Video mode switch
Fn+F5: software rfkill for wifi
For some ideapad when push Fn+F3, hardware generates Super-P keys, those key
will not be enabled by this patch.
Thanks for Dave Hansen report the problem. If CONFIG_INPUT_SPARSEKMAP is not
set, when building, you will have error message:
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!
To select INPUT_SPARSEKMAP solve this issue.
