Subject: [PATCH 5.4 14/90] vhost/scsi: fix up req type endian-ness
From: Michael S. Tsirkin <mst@...hat.com>
commit 295c1b9852d000580786375304a9800bd9634d15 upstream.
vhost/scsi doesn't handle type conversion correctly
for request type when using virtio 1.0 and up for BE,
or cross-endian platforms.
Fix it up using vhost_32_to_cpu.
