The fix is to change the evaluate to: if (event_data->ReasonCode != MPI2_EVENT_SAS_DEV_STAT_RC_INTERNAL_DEVICE_RESET && event_data->ReasonCode != MPI2_EVENT_SAS_DEV_STAT_RC_CMP_INTERNAL_DEV_RESET) return; Signed-off-by: Kashyap Desai Signed-off-by: James Bottomley --- diff --git a/drivers/scsi/mpt2sas/mpt2sas_scsih.c b/drivers/scsi/mpt2sas/mpt2sas_scsih.c index fa94f0ff7762..f3ce9b1825b1 100644 --- a/drivers/scsi/mpt2sas/mpt2sas_scsih.c +++ b/drivers/scsi/mpt2sas/mpt2sas_scsih.c @@ -4435,10 +4435,10 @@ _scsih_sas_device_status_change_event(struct MPT2SAS_ADAPTER *ioc, event_data); #endif - if (!(event_data->ReasonCode == + if (event_data->ReasonCode != MPI2_EVENT_SAS_DEV_STAT_RC_INTERNAL_DEVICE_RESET && - event_data->ReasonCode == - MPI2_EVENT_SAS_DEV_STAT_RC_CMP_INTERNAL_DEV_RESET)) + event_data->ReasonCode != + MPI2_EVENT_SAS_DEV_STAT_RC_CMP_INTERNAL_DEV_RESET) return; spin_lock_irqsave(&ioc->sas_device_lock, flags);
