- Subject: [PATCH] drm/vc4: Fix ioctl permissions for render nodes.
- Contrary to other flags to DRM_IOCTL_DEF_DRV(), which restrict usage,
- the flag for render node is an enabler (the IOCTL can't be used from
- render node if it's not present). So DRM_RENDER_ALLOW needs to be
- added to all the flags that were previously 0.
- Signed-off-by: Herve Jourdain <herve.jourdain@neuf.fr>
- Reviewed-by: Eric Anholt <eric@anholt.net>
- Fixes: 0cd3e2747662 ("drm/vc4: Add missing render node support")
- (cherry picked from commit b10c22e5f9902a329450c2027e9291b71e9f1602)
