[PATCH 11/14] platform/x86: panasonic-laptop: remove sparse_keymap_free() calls

[MichaÅ KÄpieÅ]

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 acpi_pcc_destroy_input() to one line, replace all calls
to that function with direct calls to input_unregister_device().
