From db0c25f8aadad8f0be1c6986cf1dcf874d40d79b Mon Sep 17 00:00:00 2001 From: Shawn Guo Date: Fri, 2 Mar 2018 09:12:00 +0800 Subject: [PATCH] PCI: histb: Fix error path of histb_pcie_host_enable() If clk_prepare_enable() call fails on a particular clock, we should not call clk_disable_unprepare() on this clock, but on the clocks that succeed from clk_prepare_enable() previously.
