Quoting Geert Uytterhoeven (2019-10-01 11:11:09)
> As platform_get_irq() now prints an error when the interrupt does not
> exist, a scary warning may be printed for an optional interrupt:
>
> phy_rcar_gen3_usb2 ee0a0200.usb-phy: IRQ index 0 not found
>
> Fix this by calling platform_get_irq_optional() instead.
