That's not a quick test for me, since I don't have modules enabled.
I have located my SAMA5D31 evaluation kit, and I think I will try
to get that running instead.
Meanwhile, during the weekend I made tests with a slightly permuted
"old style" struct dev_links_info, i.e. swapping place for the with
defer_sync and needs_suppliers list heads for this layout:
struct dev_links_info {
struct list_head suppliers;
struct list_head consumers;
struct list_head defer_sync;
struct list_head needs_suppliers;
bool need_for_probe;
enum dl_dev_state status;
};
This produces a new failure mode and hits a BUG. Maybe that's a hint
for someone? I have several more of these reports if someone is
interested, but they all look very similar to me.
