From 7e6f41d50ea0af9f04c17937c4060ddcafa1bc90 Mon Sep 17 00:00:00 2001 From: "Russell King (Oracle)" Date: Wed, 27 Oct 2021 10:49:19 +0100 Subject: [PATCH 2/4] net: mvpp2: remove interface checks in mvpp2_phylink_validate() As phylink checks the interface mode against the supported_interfaces bitmap, we no longer need to validate the interface mode in the validation function. Remove this to simplify it. Signed-off-by: Russell King (Oracle) Signed-off-by: David S.
