This can't be correct. "iface_no" is a u8 we read out of desc->bInterfaceNumber we still have to extend it to a u16 and convert it to a little endian 16-bit value for the req.wIndex field. If the types for the cdc notification struct are wrong, that's another story entirely. But currently they are marked as __le16 so you must resolve this first. Otherwise your changes will result in several new sparse endian warnings. I'm not applying this, even if it is correct functionally. -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo-u79uwXL29TY76Z2rM5mHXA@public.gmane.org More majordomo info at http://vger.kernel.org/majordomo-info.html
