commit b049e03ca57f238e74a79e44ffc85904db465e72 upstream.
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.
