commit fa4ae42cc60a7dea30e8f2db444b808d80862345 upstream. snp_issue_guest_request() checks the value returned by the hypervisor in sw_exit_info_2 and returns a different error depending on it. Convert those checks into a switch-case to make it more readable when more error values are going to be checked in the future. No functional changes.

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.
