+Subject: [PATCH 181/203] of: Fix dereferencing node name in debug output to be
+ safe
+
+Several locations in the of_address and of_irq code dereference the
+full_name parameter from a device_node pointer without checking if the
+pointer is valid. This patch switches to use of_node_full_name() which
+always checks the pointer.
