* Add 'struct class ide_port_class' ('ide_port' class) and a 'struct device *portdev' ('ide_port' class device) in ide_hwif_t. * Register 'ide_port' class in ide_init() and unregister it in cleanup_module(). * Create ->portdev in ide_register_port () and unregister it in ide_unregister(). * Add "delete_devices" class device attribute for unregistering IDE devices on a port and "scan" one for probing+registering IDE devices on a port. * Add ide_sysfs_register_port() helper for registering "delete_devices" and "scan" attributes with ->portdev. Call it in ide_device_add_all(). * Document IDE warm-plug support in Documentation/ide/warm-plug-howto.txt. v2: * Convert patch from using 'struct class_device' to use 'struct device'.
