[PATCH 09/14] platform/x86: msi-laptop: remove sparse_keymap_free() calls

Show all headers | View raw

As sparse_keymap_setup() now uses a managed memory allocation for the
keymap copy it creates, the latter is freed automatically.  Remove all
calls to sparse_keymap_free().

As this reduces msi_laptop_input_destroy() to one line, replace all
calls to that function with direct calls to input_unregister_device().
