| 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).
