From: Hannes Reinecke Date: Tue, 21 Dec 2021 07:20:46 +0000 (+0100) Subject: ata: libata: remove pointless VPRINTK() calls X-Git-Tag: v6.1-rc5~2147^2~72 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=e1553351d747cbcd62db01d579dff916edcc782c;p=platform%2Fkernel%2Flinux-starfive.git ata: libata: remove pointless VPRINTK() calls 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.
