From 6d11acd452fd885ef6ace184c9c70bc863a8c72f Mon Sep 17 00:00:00 2001 From: Tyler Erickson Date: Thu, 2 Jun 2022 16:51:12 -0600 Subject: [PATCH] libata: fix translation of concurrent positioning ranges Fixing the page length in the SCSI translation for the concurrent positioning ranges VPD page. It was writing starting in offset 3 rather than offset 2 where the MSB is supposed to start for the VPD page length.
