    ideapad: add hotkey support · f63409ae
    Ike Panhc authored
    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.
