gpio: ep93xx: refactor ep93xx_gpio_add_bank
- replace plain numbers with girq->num_parents in devm_kcalloc - replace plain numbers with girq->num_parents for port F - refactor i - 1 to i + 1 to make loop more readable - combine getting IRQ's loop and setting handler's into single loop Reviewed-by: Linus Walleij <linus.walleij@linaro.org> Acked-by: Alexander Sverdlin <alexander.sverdlin@gmail.com> Signed-off-by: Nikita Shubin <nikita.shubin@maquefel.me> Signed-off-by: Bartosz Golaszewski <bgolaszewski@baylibre.com>
