-/**
- *     ata_scsi_timed_out - SCSI layer time out callback
- *     @cmd: timed out SCSI command
- *
- *     Handles SCSI layer timeout.  We race with normal completion of
- *     the qc for @cmd.  If the qc is already gone, we lose and let
- *     the scsi command finish (EH_HANDLED).  Otherwise, the qc has
- *     timed out and EH should be invoked.  Prevent ata_qc_complete()
- *     from finishing it by setting EH_SCHEDULED and return
- *     EH_NOT_HANDLED.
- *
- *     TODO: kill this function once old EH is gone.
- *
- *     LOCKING:
- *     Called from timer context
- *
- *     RETURNS:
- *     EH_HANDLED or EH_NOT_HANDLED
