Because we don't check the result of init_engine_mask() while creating the engine's structure. We check it only after and indeed I removed the drm_WARN_ON() check. I think the whole process of creating the engine's structure in the intel_engines_init_mmio() can be simplified, but this goes beyong the scope of the series. Or am I missing something? Thanks, Andi
