Subject: [PATCH] net: fman: Use of_node_put(muram_node) call only once in
read_dts_node()
From: Markus Elfring <elfring@...rs.sourceforge.net>
Date: Thu, 19 Sep 2024 18:05:28 +0200
A of_node_put(muram_node) call was immediately used after a return code
check for a of_address_to_resource() call in this function implementation.
Thus use such a function call only once instead directly before the check.
This issue was transformed by using the Coccinelle software.
