[PATCH] gpio: synq: remove unused zynq_gpio_irq_reqres/zynq_gpio_irq_relres

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Arnd Bergmann <arnd@xxxxxxxx>

The driver now uses the generic request/release callbacks, so the custom
ones are no longer called. When building with -Woverride-init, gcc produces
a warning about the duplicate entries:

In file included from drivers/gpio/gpio-zynq.c:10:

  621 |                 .irq_request_resources  = gpiochip_irq_reqres,          \

      |                                           ^~~~~~~~~~~~~~~~~~~

Removing the old ones has no effect on the driver but avoids the warnings.
