commit a3058a5d upstream. During FunctionFS bind, ffs_data_get() function was called twice (in functionfs_bind() and in ffs_do_functionfs_bind()), while on unbind ffs_data_put() was called once (in functionfs_unbind() function). In result refcount never reached value 0, and ffs memory resources has been never released. Since ffs_data_get() call in ffs_do_functionfs_bind() is redundant and not neccessary, we remove it to have equal number of gets ans puts, and free allocated memory after refcount reach 0.
