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.
