From c603d04ef6826a29f50cb151cb992f256d0cf19d Mon Sep 17 00:00:00 2001 From: James Bottomley Date: Fri, 1 Dec 2006 11:25:12 -0600 Subject: [SCSI] 53c700: brown paper bag fix for auto request sense In the switch over, I forgot to set the command length, so it sends out a request sense with whatever length the prior command had (and fails badly if it wasn't 6).
