It's not a problem with this patch.
The #defines for DRM_NOUVEAU_VM_BIND_OP_MAP etc. have a ';' at the
end of each line:

struct drm_nouveau_vm_bind_op {
     __u32 op;
#define DRM_NOUVEAU_VM_BIND_OP_MAP 0x0;
#define DRM_NOUVEAU_VM_BIND_OP_UNMAP 0x1;
     __u32 flags;
#define DRM_NOUVEAU_VM_BIND_SPARSE (1 << 8);
     __u32 handle;
     __u32 pad;
     __u64 addr;
     __u64 bo_offset;
     __u64 range;
};

Do we actually ever want preprocessor directives to appear inside
definitions in the output? If not, I think this should work:

diff --git a/scripts/kernel-doc b/scripts/kernel-doc
index 3cdc7dba37e3..61425fc9645e 100755
