This is an oldish patch from the time I still thought I'd have to pass the flags in the device tree. It turned out that I don't need it anymore, so this can be totally removed from pdata and be set by the board file itself. As you saw in a later patch, I do make sure the driver sets IRQF_ONESHOT. ;) -- Cheers, Luca. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
