Subject: [PATCH net] net: qcom/emac: Fix missing clk_disable_unprepare() in error path of emac_probe
Date: Thu, 6 Aug 2020 22:06:47 +0800	[thread overview]
Message-ID: <20200806140647.43099-1-wanghai38@huawei.com> (raw)

In emac_clks_phase1_init() of emac_probe(), there may be a situation
in which some clk_prepare_enable() succeed and others fail.
If emac_clks_phase1_init() fails, goto err_undo_clocks to clean up
the clk that was successfully clk_prepare_enable().

Fixes: b9b17debc69d ("net: emac: emac gigabit ethernet controller driver")
