Colin Ian King 56f2ea0bc2 drm/radeon: fix copy of uninitialized variable back to userspace 
commit 8dbc2ccac5a65c5b57e3070e36a3dc97c7970d96 upstream.

Currently the ioctl command RADEON_INFO_SI_BACKEND_ENABLED_MASK can
copy back uninitialised data in value_tmp that pointer *value points
to. This can occur when rdev->family is less than CHIP_BONAIRE and
less than CHIP_TAHITI.  Fix this by adding in a missing -EINVAL
so that no invalid value is copied back to userspace.

Addresses-Coverity: ("Uninitialized scalar variable)
Cc: stable@vger.kernel.org # 3.13+
Fixes: 439a1cfffe ("drm/radeon: expose render backend mask to the userspace")

README 

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.
