From fa7fe29a645b4da08efe8ff2392898b88f9ded9f Mon Sep 17 00:00:00 2001 From: Steven Price Date: Mon, 25 Mar 2019 17:37:22 +0000 Subject: firmware: arm_scmi: fix of_node leak in scmi_mailbox_check of_parse_phandle_with_args() requires the caller to call of_node_put() on the returned args->np pointer. Otherwise the reference count will remain incremented. However, in this case, since we don't actually use the returned pointer, we can simply pass in NULL.
