Done now. It was already similar to your version and after
addressing Mark's comment about error handling, I now squashed
it into this:

        if (cpu_is_pxa27x()) {
                /* Assert reset using GPIOD_OUT_HIGH, because reset is GPIO_ACTIVE_LOW */
                rst_gpio = devm_gpiod_get_optional(&dev->dev, "reset",
                                                   GPIOD_OUT_HIGH);
                if (IS_ERR(rst_gpio))
                        return dev_err_probe(&dev->dev, PTR_ERR(rst_gpio),
                                             "reset gpio failed\n");
                ...
        }
