A few link problems, two from device tree:

of_graph_parse_endpoint() commit fd9fdb78a9bf8

of_get_next_parent() was not exported until commit 6695be6863b75

nsecs_to_jiffies() was not exported until commit d560fed6abe0f

How would you fix those?

I will try building a kernel with CONFIG_OF=n

Regards.
