They are used:
+       spitz_gpio_leds[0].gpiod = leds->desc[0];
+       spitz_gpio_leds[1].gpiod = leds->desc[1];

The descriptors are passed to the leds-gpio driver.

But wait: no.

This whole thing:

+static struct gpio_descs *leds;
+
(...)
+       leds = gpiod_get_array_optional(&spitz_led_device.dev,
+                       NULL, GPIOD_ASIS);
+       spitz_gpio_leds[0].gpiod = leds->desc[0];
+       spitz_gpio_leds[1].gpiod = leds->desc[1];

Just delete all that.

The leds-gpio driver will request and use the lines.

It was just so unorthodox that I missed it. Adding the descriptor
table is enough.
