Subject: [PATCH 4/7] ideapad: select INPUT_SPARSEKMAP

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.
