Aww crap, this breaks debug builds.
ERROR: modpost: "intel_runtime_pm_put" [drivers/gpu/drm/i915/kvmgt.ko] undefined!
ERROR: modpost: "i915_fence_ops" [drivers/gpu/drm/i915/kvmgt.ko] undefined!
make[1]: *** [scripts/Makefile.modpost:134: modules-only.symvers] Error 1
make[1]: *** Deleting file 'modules-only.symvers'
make: *** [Makefile:1749: modules] Error 2
The first is triggered with CONFIG_DRM_I915_DEBUG_RUNTIME_PM=y, the
latter with CONFIG_DRM_I915_DEBUG_GEM=y.
Please add the proper fix on top of the topic branch, and send an
additional pull request. Looks like exports will do it.
On that note, I'm wondering about the use of
EXPORT_SYMBOL_NS_GPL(). It's between two MIT licensed modules after
all. Maybe just EXPORT_SYMBOL_NS()?
BR,
Jani.
