[ Upstream commit 907c5bbb514a4676160e79764522fff56ce3448e ]
Early exits from for_each_available_child_of_node() should decrement the node reference counter. Reported by Coccinelle:
drivers/memory/atmel-ebi.c:593:1-33: WARNING: Function "for_each_available_child_of_node" should have of_node_put() before return around line 604.
