It is clear from inspection that do_divide_error is only called with
TRAP_DIVZERO_ERROR or TRAP_DIVOVF_ERROR, as that is the way
set_exception_table_vec is called. So let gcc know the other cases
should not be considered by returning in all other cases.
This removes the warning and let's the code continue to build.

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
