We already sanitize the guest's PSCI version when it is being written by userspace, rejecting unsupported version numbers. Additionally, the 'minor' parameter to kvm_psci_1_x_call() is a constant known at compile time for all callsites. Though it is benign, the additional check against the PSCI kvm_psci_1_x_call() is unnecessary and likely to be missed the next time KVM raises its maximum PSCI version. Drop the check altogether and rely on sanitization when the PSCI version is set by userspace. No functional change intended.

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.
