Oh. I just realized that struct arm_pmu_cpu doesn't even exist. This still compiles though because we're dealing with a void pointer. Perhaps its better to just do dev = *(void **)dev; here. Can you fix that up when applying? Otherwise I'll do it on the next send if there are more comments.
+ armpmu = dev; + plat_device = armpmu->plat_device; + plat = dev_get_platdata(&plat_device->dev);
