From b2033a05a7197f5ddef617be8f510c9957a82553 Mon Sep 17 00:00:00 2001 From: Vladimir Oltean Date: Fri, 15 Apr 2022 18:46:23 +0300 Subject: [PATCH] net: dsa: use dsa_tree_for_each_user_port in dsa_slave_change_mtu Use the more conventional iterator over user ports instead of explicitly ignoring them, and use the more conventional name "other_dp" instead of "dp_iter", for readability.
