Gentle ping, this patch didn't make it into 4.1-rc1.

Sorry Robert, this fell through the cracks. VExpress gets very few

Best regards,
Liviu

I'm testing on qemu (and not even the latest one), so this might be a
reason.

OK, I tried on my CA9 coretile and don't see these errors on it either.
However the "... creating of_node link" is present on both and I will
look at that issue.

OK, I was able to debug this, it boils down to initcall ordering.
Both of_init where the firmware sysfs is initialized and
vexpress_sysreg_init are at same core_initcall level. Needs some
thinking and more time to fix this.

Did you find out something in the meantime?
I just tested 4.1-rc3 and the issues are still confirmed.

I posted the patch but not yet pulled in mainline yet [1]
