I have another module mlx-platform, which is reviewed now (I also got a number feedbacks from you on this matter).
I want to activate mlxcpld-hotplug from this module. 
Like

/* Platform hotplug default data */
static struct mlxcpld_hotplug_platform_data mlxplat_mlxcpld_hotplug_default_data = {
 
/* Platform hotplug MSN21xx system family data*/
static struct mlxcpld_hotplug_platform_data mlxplat_mlxcpld_hotplug_msn21xx_data = {
...
	priv->pdev_hotplug = platform_device_register_resndata(
				&mlxplat_dev->dev, "mlxcpld-hotplug", -1,
				mlxplat_mlxcpld_hotplug_resources,
				ARRAY_SIZE(mlxplat_mlxcpld_hotplug_resources),
				mlxplat_hotplug, sizeof(*mlxplat_hotplug));

But I can't add this code to mlx-platfrom, until this one is not accepted.

Thanks,

Vadim.
