From 1dc3485247170d3b88a21cadee7f7da1f0433495 Mon Sep 17 00:00:00 2001 From: Gerd Hoffmann Date: Wed, 23 Oct 2019 08:25:37 +0200 Subject: [PATCH] drm/virtio: fix byteorder handling in virtio_gpu_cmd_transfer_{from, to}_host_3d functions Be consistent with the rest of the code base. No functional change. v2: - fix sparse warnings for virtio_gpu_cmd_transfer_to_host_2d call. - move convert_to_hw_box helper function.
