We didn't solve that problem.

The reason is that changing the platform from chained to regular handler
involves of course changing all the other drivers in the irqchip hierarchy
since chained is an all-or-nothing approach, and that needs to happen
over the whole set of Qualcomm drivers.

Sooner or later I guess I will get to it unless Bjorn or Brian or someone
else beats me to it.
