Subject: [PATCH v2] phy: renesas: rcar-gen3-usb2: Use platform_get_irq_optional() for optional irq
Date: Wed, 16 Oct 2019 16:27:33 +0200	[thread overview]
Message-ID: <20191016142733.28387-1-geert+renesas@glider.be> (raw)

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.

Fixes: 7723f4c5ecdb8d83 ("driver core: platform: Add an error message to platform_get_irq*()")
