Subject: [PATCH] pinctrl: pinconf-generic: add missing of_node_put()
Git-commit: 5ead93289815a075d43c415e35c8beafafb801c9
Patch-mainline: v6.2-rc1
References: git-fixes
of_node_put() needs to be called when jumping out of the loop, since
for_each_available_child_of_node() will increase the refcount of node.
Fixes: c7289500e29d ("pinctrl: pinconf-generic: scan also referenced phandle node")
