There are some hosts (e.g. with a popular, proprietary operating system), which issue setup requests directed at a device even though they mean setup requests directed at a particular interface (usb function).
This series adds optional for_device attribute in struct usb_configuration. If the attribute is non-NULL, the USB function it points to is used as the last fallback when searching for handlers in composite_setup(). If the attribute is NULL, then the composite_setup() behaviour remains unchanged. The second patch adds a method to get/set the function to be used as for_device in a configfs-composed gadget. Since Felipe closed his tree for 3.18 this is meant for 3.19.
