[PATCH 8/9] scsi: Do not display buffer pointers in scsi_log_send()

[Hannes Reinecke <hare@suse.de>]

scsi_log_send() would display buffer pointer for higher
logging levels. This is not only of questionable value
but also exposes kernel pointer to userspace, which is
discouraged in some setups. So drop this message
altogether.
