I still see these errors with 4.1-rc1:

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.

Ah sorry, forgot to include you or your Reported-by(will
fix that if/when I have to repost a newer version)
I posted the patch but not yet pulled in mainline yet [1]

Regards,
Sudeep
