It should read: "DT-enabled platforms, where the irqchip driver for the brigde interrupt controller is available, can handle the watchdog IRQ properly. Therefore, we request the interrupt and add a dummy handler that merely calls panic()". I guess we can re-phrase it be a bit more readable. Why does th commit title looks wrong? By requesting the IRQ we are "handling it", no? > > > > This is done in order to have an initial 'ack' of the interruption, > > interruption -> interrupt > Right. -- Ezequiel Garc?a, Free Electrons Embedded Linux, Kernel and Android Engineering http://free-electrons.com
