Subject: [PATCH v12 04/13] PCI: imx6: Move imx6_pcie_clk_disable() earlier
Date: Wed, 15 Jun 2022 18:15:42 -0500	[thread overview]
Message-ID: <20220615231551.1054753-5-helgaas@kernel.org> (raw)
In-Reply-To: <20220615231551.1054753-1-helgaas@kernel.org>

From: Richard Zhu <hongxing.zhu@nxp.com>

Move imx6_pcie_clk_disable() earlier to be near other clock-related
functions.  No functional change intended.

[bhelgaas: reorder patch so pure moves are earlier]
