[igt-dev] [PATCH i-g-t v2 6/6] drm-uapi/virtgpu: sync with drm-next

[Kamil Konieczny]

From: Simon Ser <contact at emersion.fr>

Sync virtgpu drm-uapi header with drm-next commit ("52920704df878050123dfeb469aa6ab8022547c1")

v1: split virtgpu and vmwgfx to separate patch (Kamil)
v2: correct spelling in commit description, split virtgpu
  into separate patch, added new e-mails to Cc (Kamil)
