SPARSE_KEYMAP_FREE(9)						  Input Subsystem					     SPARSE_KEYMAP_FREE(9)

NAME
       sparse_keymap_free - free memory allocated for sparse keymap

SYNOPSIS
       void sparse_keymap_free(struct input_dev * dev);

ARGUMENTS
       dev
	   Input device using sparse keymap

DESCRIPTION
       This function is used to free memory allocated by sparse keymap in an input device that was set up by sparse_keymap_setup.

NOTE
       It is safe to cal this function while input device is still registered (however the drivers should care not to try to use freed keymap and
       thus have to shut off interrups/polling before freeing the keymap).
