Subject: [PATCH 1/2] powerpc/82xx: Delete an unnecessary of_node_put() call in pq2ads_pci_init_irq()
Date: Tue, 27 Aug 2019 10:26:43 +0200	[thread overview]
Message-ID: <9c060a41-438b-6fb8-d549-37c72fae4898@web.de> (raw)
In-Reply-To: <6dc7d70e-8a40-46ab-897b-d2eaf9a87d77@web.de>

A null pointer would be passed to a call of the function “of_node_put”
immediately after a call of the function “of_find_compatible_node” failed
at one place.
Remove this superfluous function call.

This issue was detected by using the Coccinelle software.
