                                          ^
"i" is uninitialized now.

Also in the initializer it has "struct device_node *endpoint = NULL;"
which is unnecessary now.  And at the end it has:

	of_node_put(endpoint);
	return pdata;

Since endpoint is NULL this was always a pointless no-op but now it's
more obvious, so lets delete that.
