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
       interrupts/polling before freeing the keymap).
