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);
}
