-/**
- * scsi_normalize_sense - normalize main elements from either fixed or
- * descriptor sense data format into a common format.
- *
- * @sense_buffer: byte array containing sense data returned by device
- * @sb_len: number of valid bytes in sense_buffer
- * @sshdr: pointer to instance of structure that common
- * elements are written to.
- *
- * Notes:
- * The "main elements" from sense data are: response_code, sense_key,
- * asc, ascq and additional_length (only for descriptor format).
- *
- * Typically this function can be called after a device has
- * responded to a SCSI command with the CHECK_CONDITION status.
- *
- * Return value:
- * true if valid sense data information found, else false;
