It may be possible for the sum of the values derived from i915_ggtt_offset() and __get_parent_scratch_offset()/ i915_ggtt_offset() to go over the u32 limit before being assigned to wq offsets of u64 type. Mitigate these issues by expanding one of the right operands to u64 to avoid any overflow issues just in case. Found by Linux Verification Center (linuxtesting.org) with static analysis tool SVACE.

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 reStructuredText 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.
