Subject: cmd: scsi: Fix null pointer dereference in 'scsi reset'
X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=db13a768a07b31b4955db934f3d55d2c77335bcc;p=u-boot.git

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.
