Yes, I am using customized version of msm-4.9 kernel based on Android.
And yes the irqchip driver is: irq-gic-v3, which I can see from config.
But, what I wanted to know is, how to find out which driver module
(hopefully under: /drivers/soc/qcom/) that register with this
irq_chip, is getting triggered at the time of crash ?
So, that I can implement irq_hold function for it, which is the cause of crash.
