MODULE_DESCRIPTION("Marvell EBU PCIe driver");
This removes the subsys_initcall from the driver and converts it to a normal platform_driver. Also, drvdata is set and a remove functions is added to disable the clock and free resources. As pci driver removal currently is not supported, set .suppress_bind_attrs to permit unbinding. Signed-off-by: Sebastian Hesselbarth <sebastian.hesselbarth@gmail.com> --- Changelog: v1->v2: - do not add .remove and set .suppress_bind_attrs to permit currently unsupported driver unloading/unbinding (Reported by Thierry Reding and Thomas Petazzoni) - Note: I left the platform_set_drvdata(), as we will require that later for device removal.
