From: Arnd Bergmann <arnd@xxxxxxxx> When ACPI is disabled, i915 fails to build because of a missing declaration: drivers/gpu/drm/i915/i915_driver.c: In function 'i915_driver_hw_probe': drivers/gpu/drm/i915/i915_driver.c:556:9: error: implicit declaration of function 'intel_opregion_cleanup'; did you mean 'intel_opregion_setup'? [-Werror=implicit-function-declaration] 556 | intel_opregion_cleanup(dev_priv); Add another empty dummy helper next to intel_opregion_setup().
