+ }of_get_child_by_name() takes a reference to an OF node, you must release it in the error path.

+ }Likewise, but here you have to release both "devices" and "child". You're going to have to fix this OF node refcount problem for this entire probe routine. -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo-u79uwXL29TY76Z2rM5mHXA@public.gmane.org More majordomo info at http://vger.kernel.org/majordomo-info.html
