This is totally wrong. The gpio driver needs these interrupts, and will register a chained interrupt handle for these. Don't mess around with them. Here is the code in the driver: /* Setup the interrupt handlers. Each chip can have up to 4 * interrupt handlers, with each handler dealing with 8 GPIO * pins. */ for (i = 0; i < 4; i++) { int irq = platform_get_irq(pdev, i); if (irq < 0) continue; irq_set_handler_data(irq, mvchip); irq_set_chained_handler(irq, mvebu_gpio_irq_handler); } Andrew -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
