Subject: [PATCH] powerpc/kexec: fix for_each_child.cocci warning
Date: Tue, 3 Aug 2021 16:59:55 +0200 (CEST) [thread overview]
Message-ID: <alpine.DEB.2.22.394.2108031654080.17639@hadrien> (raw)
From: kernel test robot <lkp@intel.com>
for_each_node_by_type should have of_node_put() before return.

The code seems to have been this way since the beginning of time. Perhaps
the of_node_put is a no op for this code?
