If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. >From 8f269102baf788aecfcbbc6313b6bceb54c9b990 Mon Sep 17 00:00:00 2001 From: Joakim Zhang <qiangqing.zhang@xxxxxxx> Date: Wed, 16 Jun 2021 17:10:24 +0800 Subject: net: stmmac: disable clocks in stmmac_remove_config_dt() From: Joakim Zhang <qiangqing.zhang@xxxxxxx> commit 8f269102baf788aecfcbbc6313b6bceb54c9b990 upstream. Platform drivers may call stmmac_probe_config_dt() to parse dt, could call stmmac_remove_config_dt() in error handing after dt parsed, so need disable clocks in stmmac_remove_config_dt(). Go through all platforms drivers which use stmmac_probe_config_dt(), none of them disable clocks manually, so it's safe to disable them in stmmac_remove_config_dt().
