| Subject: drm/virtio: fix framebuffer sparse warning |
| |
| From: Gerd Hoffmann <kraxel@redhat.com> |
| |
| |
| [ Upstream commit 71d3f6ef7f5af38dea2975ec5715c88bae92e92d ] |
| |
| virtio uses normal ram as backing storage for the framebuffer, so we |
| should assign the address to new screen_buffer (added by commit |
| 17a7b0b4d9749f80d365d7baff5dec2f54b0e992) instead of screen_base. |
