From 244ccc8e866b23689fab9f6aa0da01cd71349cc9 Mon Sep 17 00:00:00 2001 From: Christophe JAILLET Date: Mon, 7 Jun 2021 22:40:09 +0800 Subject: [PATCH] net: mdio: thunder: Fix a double free issue in the .remove function [ Upstream commit a93a0a15876d2a077a3bc260b387d2457a051f24 ] 'bus->mii_bus' have been allocated with 'devm_mdiobus_alloc_size()' in the probe function. So it must not be freed explicitly or there will be a double free. Remove the incorrect 'mdiobus_free' in the remove function.
