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).
