From e6e918d4eb93f43e770fbc2a0881686e350e1a1f Mon Sep 17 00:00:00 2001 From: Heiner Kallweit Date: Wed, 6 Jan 2021 14:03:40 +0100 Subject: net: phy: replace mutex_is_locked with lockdep_assert_held in phylib Switch to lockdep_assert_held(_once), similar to what is being done in other subsystems. One advantage is that there's zero runtime overhead if lockdep support isn't enabled.
