From 89df20d951b310f3e33422554054ae6e58a3c7a9 Mon Sep 17 00:00:00 2001 From: Hans de Goede Date: Tue, 20 May 2014 11:38:18 +0200 Subject: [PATCH] stmmac: Remove unbalanced clk_disable call The stmmac_open call was calling clk_disable_unprepare on phy init failure, but it never calls clk_prepare_enable, this causes a WARN_ON in the clk framework to trigger if for some reason phy init fails.
