From c52866655558e5fc87ceae8aac528a7e410c8a77 Mon Sep 17 00:00:00 2001 From: Vivien Didelot Date: Mon, 6 Nov 2017 16:11:50 -0500 Subject: [PATCH] net: dsa: use of_for_each_phandle The OF code provides a of_for_each_phandle() helper to iterate over phandles. Use it instead of arbitrary iterating ourselves over the list of phandles hanging to the "link" property of the port's device node. The of_phandle_iterator_next() helper calls of_node_put() itself on it.node. Thus We must only do it ourselves if we break the loop. Signed-off-by: Vivien Didelot Signed-off-by: David S.
