Subject: [PATCH] soc: mediatek: mtk-svs: Call of_node_put(np) only once in
svs_get_subsys_device()
From: Markus Elfring <elfring@...rs.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.
