+Subject: interconnect: fix mem leak when freeing nodes
+
+From: Johan Hovold <johan+linaro@kernel.org>
+
+commit a5904f415e1af72fa8fe6665aa4f554dc2099a95 upstream.
+
+The node link array is allocated when adding links to a node but is not
+deallocated when nodes are destroyed.
+
+Fixes: 11f1ceca7031 ("interconnect: Add generic on-chip interconnect API")
