[ Upstream commit1c3ace2b8b] Although harmless, the return statement in kvm_unexpected_el2_exception is rather confusing as the function itself has a void return type. The C standard is also pretty clear that "A return statement with an expression shall not appear in a function whose return type is void". Given that this return statement does not seem to add any actual value, let's not pointlessly violate the standard. Build-tested with GCC 10 and CLANG 13 for good measure, the disassembled code is identical with or without the return statement.

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.
