  *
- * This interface is primarily intended for use with legacy drivers which
- * probe hardware directly.  Because such drivers create sysfs device nodes
- * themselves, rather than letting system infrastructure handle such device
- * enumeration tasks, they don't fully conform to the Linux driver model.
- * In particular, when such drivers are built as modules, they can't be
- * "hotplugged".

- * Returns &struct platform_device pointer on success, or ERR_PTR() on error.
