In fact, is the best way to do it to have a prototype like:

	int security_key_getsecurity(struct key *key, char **_buffer);

Where the buffer is allocated by this function and attached to *_buffer and
the length returned if successful (though that last is unnecessary if a
NUL-terminated string is being returned); and if an error occurs, then that is
returned instead.
