NAME

6       sparse_keymap_free - free memory allocated for sparse keymap
7

SYNOPSIS

9       void sparse_keymap_free(struct input_dev * dev);
10

ARGUMENTS

12       dev
13           Input device using sparse keymap
14

DESCRIPTION

16       This function is used to free memory allocated by sparse keymap in an
17       input device that was set up by sparse_keymap_setup.
18

NOTE

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