When building with -Woverride-init, gcc produces a warning about the duplicate entries: In file included from drivers/gpio/gpio-zynq.c:10: include/linux/gpio/driver.h:621:43: error: initialized field overwritten [-Werror=override-init] 621 | .irq_request_resources = gpiochip_irq_reqres, \ | ^~~~~~~~~~~~~~~~~~~ drivers/gpio/gpio-zynq.c:611:9: note: in expansion of macro 'GPIOCHIP_IRQ_RESOURCE_HELPERS' 611 | GPIOCHIP_IRQ_RESOURCE_HELPERS, | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~ include/linux/gpio/driver.h:621:43: note: (near initialization for 'zynq_gpio_level_irqchip.irq_request_resources') 621 | .irq_request_resources = gpiochip_irq_reqres, \ | ^~~~~~~~~~~~~~~~~~~ drivers/gpio/gpio-zynq.c:625:9: note: in expansion of macro 'GPIOCHIP_IRQ_RESOURCE_HELPERS' 625 | GPIOCHIP_IRQ_RESOURCE_HELPERS, | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~ include/linux/gpio/driver.h:622:43: error: initialized field overwritten [-Werror=override-init] 622 | .irq_release_resources = gpiochip_irq_relres | ^~~~~~~~~~~~~~~~~~~ Removing the old ones has no effect on the driver but avoids the warnings.
