From db13a768a07b31b4955db934f3d55d2c77335bcc Mon Sep 17 00:00:00 2001 From: Bin Meng Date: Sat, 17 Jun 2017 06:36:00 -0700 Subject: [PATCH] cmd: scsi: Fix null pointer dereference in 'scsi reset' During 'scsi reset', scsi_bus_reset() is called with udevice pointed to NULL, which causes exception. As a temporary fix, disable the call for DM SCSI for now.
