Move the call to platform_get_irq() earlier in the probe function and check for its return value: if no interrupt is specified, it wouldn't make sense to try to call devm_request_irq() so, in that case, we can simply return early. Moving the platform_get_irq() call also makes it possible to use one less goto, as clocks aren't required at that stage.
