Hi Ingi, Rob,

With this patch we will be leaking of_node when parsing succeeds.
I think that "return 0" should be removed. I can remove it and apply,
provided that Rob's ack is still in force with this. Rob?

Best Regards,
Jacek Anaszewski

The refcount of device_node increases after of_node_get() is called.
So, a break out of the loop requires of_node_put().

This patch adds missing of_node_put() when loop breaks.
