commit 53b16dd6ba5cf64ed147ac3523ec34651d553cb0 upstream.
The doc says:
"The characteristics of a specific redistributor region can
be read by presetting the index field in the attr data.
Only valid for KVM_DEV_TYPE_ARM_VGIC_V3"
Unfortunately the existing code fails to read the input attr data.
Fixes: 04c110932225 ("KVM: arm/arm64: Implement KVM_VGIC_V3_ADDR_TYPE_REDIST_REGION")

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.
