All banks with GPIO interrupts should be at beginning of bank array and without any other types of banks between them. This order is expected by exynos_eint_gpio_irq, when doing interrupt group to bank translation. Otherwise, kernel NULL pointer dereference would happen when trying to handle interrupt, due to wrong bank being looked up. Observed on s5pv210, when trying to handle gpj0 interrupt, where kernel was mapping it to gpi bank.
