From 1416ea0ddc1463fb8c9cf12b48f3df82a327e356 Mon Sep 17 00:00:00 2001 From: Heiner Kallweit Date: Sun, 6 Mar 2022 15:22:34 +0100 Subject: [PATCH] net: mdio-mux: add bus name to bus id In case of DT-configured systems it may be hard to identify the PHY interrupt in the /proc/interrupts output. Therefore add the name to the id to make clearer that it's about a device on a muxed mdio bus.
