This still has another compile problem:

ERROR: modpost: "intel_runtime_pm_put" [vmlinux] is a static EXPORT_SYMBOL_GPL

Because:

#if IS_ENABLED(CONFIG_DRM_I915_DEBUG_RUNTIME_PM)
void intel_runtime_pm_put(struct intel_runtime_pm *rpm, intel_wakeref_t wref);
#else
static inline void
intel_runtime_pm_put(struct intel_runtime_pm *rpm, intel_wakeref_t wref)
{
        intel_runtime_pm_put_unchecked(rpm);
}
#endif

Looks like it happens if CONFIG_DRM_I915_DEBUG_RUNTIME_PM=n

I think you probably want to #ifdef the export in the same way:
