The original composite gadget tries to bind several functions one by one, and the final result is decided by the last function. That is, if binding of the last function (ecm or eem) is ok, return value is 0. Or return value will be non-zero and the whole gadget will not be functional. For example, number of endpoints is not enough to support all the functions on some platform, and the last func binding API will return -ENODEV, which lead to the whole gadget enabling failure. However, the previous functions should still be able to be used. This patch is used to handle this more flexibly. As long as one of the functions is bound succesfully, return value will be 0.
