Subject: [PATCH v5 3/6] PCI: imx6: PCI: imx6: Move imx6_pcie_clk_disable() earlier
Date: Wed, 5 Jan 2022 15:43:19 +0800 [thread overview]
Message-ID: <1641368602-20401-4-git-send-email-hongxing.zhu@nxp.com> (raw)
In-Reply-To: <1641368602-20401-1-git-send-email-hongxing.zhu@nxp.com>
Just move the imx6_pcie_clk_disable() to an earlier place without function
changes, since it wouldn't be only used in imx6_pcie_suspend_noirq() later.
