locking, hpet: annotate false positive warning
Alexander Beregalov reported that this warning is caused by the HPET code: > hpet0: at MMIO 0xfed00000, IRQs 2, 8, 0 > hpet0: 3 comparators, 64-bit 14.318180 MHz counter > ODEBUG: object is on stack, but not annotated > ------------[ cut here ]------------ > WARNING: at lib/debugobjects.c:251 __debug_object_init+0x2a4/0x352() > Bisected down to 26afe5f2fbf06ea0765aaa316640c4dd472310c0 > (x86: HPET_MSI Initialise per-cpu HPET timers) The commit is fine - but the on-stack workqueue entry needs annotation.
