[PATCH 1/2] powerpc/82xx: Delete an unnecessary of_node_put() call in pq2ads_pci_init_irq()

[Markus Elfring]

From: Markus Elfring <elfring at users.sourceforge.net>
Date: Tue, 27 Aug 2019 08:44:20 +0200

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.
