[SCSI] mpt2sas: Corrected conditional checks for Internal device Reset
bug fix in the handling of the internal device reset event The reason code check in scsih_sas_device_status_change_event never evaluates as true for internal device reset, hence driver never quiesce s IO when firmware is sending a device reset. 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 <kashyap.desai@lsi.com> Signed-off-by: James Bottomley <James.Bottomley@suse.de>
