Subject: [PATCH] drm: Allow DRM_IOCTL_MODE_CREATE_DUMB on render nodes
Due to a change in Mesa, the render node ends up being picked
instead of the primary node when using Exynos DRM kmsro. In turn,
this results in that dumb buffers cannot be allocated with
DRM_IOCTL_MODE_CREATE_DUMB, so many applications crash. This works
around that by allowing dumb buffers to be created by render nodes.
