Enabling kernel-doc warnings in commit aaee4bbe8a1a ("drm/i915: enable
kernel-doc warnings for CONFIG_DRM_I915_WERROR=y") actually only covers
the .c files. And it's good for avoiding warnings in W= builds. However,
we need something more to check for kernel-doc issues in headers. Add it
as part of the existing HDRTEST.
We have tons of issues, and this unleashes warnings galore on
CONFIG_DRM_I915_WERROR=y. It doesn't fail the build because (at least
for now) we don't pass -Werror to kernel-doc.
