Sorry I checked log and didn't find any 0day reports for that error.

It actually hit the errors several times:

drivers/soc/renesas/r8a77970-sysc.c:14:11: sparse: unable to open 'dt-bindings/power/r8a77970-sysc.h'

So the robot is not working well in that case, I'll work with Philip
to get that fixed.
