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.
