Subject: [PATCH] vhost/scsi: fix up req type endian-ness
Date: Fri, 10 Jul 2020 06:48:51 -0400	[thread overview]
Message-ID: <20200710104849.406023-1-mst@redhat.com> (raw)

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.
