Then, do you mean the following?

static int __exit exynos_pcie_remove(struct platform_device *pdev)
{
        struct pcie_port *pp = platform_get_drvdata(pdev);

        clk_disable_unprepare(pp->bus_clk);
        clk_disable_unprepare(pp->clk);

        return 0;
}

static struct platform_driver exynos_pcie_driver = {
        .remove = __exit_p(exynos_pcie_remove),

[.....]

/* Exynos PCIe driver does not allow module unload */

static int __init pcie_init(void)
{
        hook_fault_code(16 + 6, exynos_pcie_abort, SIGBUS, 0,
                        "imprecise external abort");

        platform_driver_probe(&exynos_pcie_driver, exynos_pcie_probe);

        return 0;
}
subsys_initcall(pcie_init);
