From 39daab23768895c32b82e153c21a7955ae7dacb8 Mon Sep 17 00:00:00 2001 From: Marek Vasut Date: Sat, 23 May 2020 17:55:50 +0200 Subject: [PATCH] net: eepro100: Pass device private data into mdiobus Instead of doing ethernet device lookup by name every time there is an MDIO access, pass the driver private data via mdiobus priv to the MDIO bus accessors.
