[PATCH 5.15 018/570] ata: libata: remove pointless VPRINTK() calls

Greg Kroah-Hartman

From: Hannes Reinecke <hare@suse.de>

[ Upstream commit e1553351d747cbcd62db01d579dff916edcc782c ]

Most of the information is already covered by tracepoints
(if not downright pointless), so remove the VPRINTK() calls.
And while we're at it, remove ata_scsi_dump_cdb(), too,
as this information can be retrieved from scsi tracing.
