Subject: [PATCH] soc: mediatek: mtk-svs: Call of_node_put(np) only once in svs_get_subsys_device()
Date: Tue, 24 Sep 2024 20:08:15 +0200	[thread overview]
Message-ID: <884f0a5d-e6d3-47dc-8a9e-201bb86b271f@web.de> (raw)

From: Markus Elfring <elfring@users.sourceforge.net>
Date: Tue, 24 Sep 2024 20:00:09 +0200

An of_node_put(np) call was immediately used after a pointer check
for a of_find_device_by_node() call in this function implementation.
Thus call such a function only once instead directly before the check.

This issue was transformed by using the Coccinelle software.
