Subject: [PATCH v7 3/8] PCI: imx6: Move imx6_pcie_clk_disable() earlier
Date:   Wed, 16 Feb 2022 14:20:58 +0800
Message-Id: <1644992463-14467-4-git-send-email-hongxing.zhu@nxp.com>
In-Reply-To: <1644992463-14467-1-git-send-email-hongxing.zhu@nxp.com>
References: <1644992463-14467-1-git-send-email-hongxing.zhu@nxp.com>
Precedence: bulk

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.
