Subject: [PATCH -next] PCI: dra7xx: Add missing of_node_put() in dra7xx_pcie_init_irq_domain()
Date: Mon, 17 Oct 2016 14:54:37 +0000	[thread overview]
Message-ID: <1476716077-30379-1-git-send-email-weiyj.lk@gmail.com> (raw)

From: Wei Yongjun <weiyongjun1@huawei.com>

This node pointer is returned by of_get_next_child() with refcount
incremented in this function. of_node_put() on it before exitting
this function on error.

This is detected by Coccinelle semantic patch.
