This will also make sure that when DT support is added,
"gpios" property can be used as no con_id labels are
provided.

-	gpio = devm_gpiod_get_index(&pdev->dev, rfkill->reset_name, 0);
+	gpio = devm_gpiod_get_index(&pdev->dev, NULL, 0);

I think the correct fix here is to look up the GPIO by name rather than
by index, but simply hard-code the name rather than generating it with
sprintf(). Index lookups are hard to expand compatibly, but named-based
lookups scale much better.

In other words, I rather specifically disagree with using a plain
"gpios" property in any future DT binding, but would strongly prefer
e.g. reset-gpios/shutdown-gpios or gpios/gpio-names.

Still, I guess I don't object too much.
