Subject: [PATCH] media: c8sectpfe: Call of_node_put(i2c_bus) only once in c8sectpfe_probe()
Date: Fri, 4 Oct 2024 15:56:40 +0200	[thread overview]
Message-ID: <5d8222c5-d564-4e27-9a85-ec4a526e84f8@web.de> (raw)

From: Markus Elfring <elfring@users.sourceforge.net>
Date: Fri, 4 Oct 2024 15:50:15 +0200

An of_node_put(i2c_bus) call was immediately used after a pointer check
for an of_find_i2c_adapter_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.
