If the primary GT is disabled via configfs, we need to make sure that we don't search for this workaround on a NULL xe_gt pointer. Since we can disable the primary GT only on igpu platforms, the media GT is the one we'd want to check anyway for this workaround. The ternary operators in ggtt_update_access_counter() were getting a bit long/complicated, so rewrite them with regular if/else statements. While we're at it, throw in a couple extra assertions to make sure that we're truly picking the expected GT according to igpu/dgpu type. v2: - Adjust indentation/wrapping; it's easier to read this with longer, unwrapped lines. (Lucas) - Tweak wording of commit message to remove ambiguity.

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.
