Subject: [PATCH v3 1/2] PCI: histb: Fix error path of histb_pcie_host_enable()
Date: Fri, 2 Mar 2018 09:12:00 +0800 [thread overview]
Message-ID: <1519953121-28218-2-git-send-email-shawn.guo@linaro.org> (raw)
In-Reply-To: <1519953121-28218-1-git-send-email-shawn.guo@linaro.org>
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.
