Subject: [PATCH net] net: stmmac: disable clocks in stmmac_remove_config_dt()
Date: Wed, 16 Jun 2021 17:10:24 +0800	[thread overview]
Message-ID: <20210616091024.13412-1-qiangqing.zhang@nxp.com> (raw)

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().

Fixes: commit d2ed0a7755fe ("net: ethernet: stmmac: fix of-node and fixed-link-phydev leaks")
