Thanks for the report.

This is only visible with CONFIG_DRM_I915_WERROR=y which depends on
COMPILE_TEST=n. We use the "HDRTEST" and -Werror for development and CI
to keep the driver clean, but it's not really intended for general
consumption. Usually when something like this even hits the tree it's
because of a merge mishap somewhere down the line.

BR,
Jani.
