The USB gadget code is the only code that every tried to utilize the 2nd argument of the aio completions, but there are strong suspicions that it was never actually used by anything on the userspace side. Out of the 3 cases that touch it, two of them just pass in the same as res, and the last one passes in error/transfer in res like any other normal use case. Remove the 2nd argument, pass 0 like the rest of the in-kernel users of kiocb based IO.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
