[ Upstream commit d1f2c82f3b1f428bdc0933dde52fb93ae796d4ee ]
In the blamed commit, it removes the duplicate of_node assignment in the driver. But the driver uses this before calling into of_gpio_dev_init to determine if it needs to assign an IRQ chip to the GPIO. The fixes consists in using the platform_get_irq_optional
