Subject: [PATCH] net: mvmdio: avoid error message for optional IRQ
Per the dt-binding the interrupt is optional so use
platform_get_irq_optional() instead of platform_get_irq(). Since
commit 7723f4c5ecdb ("driver core: platform: Add an error message to
platform_get_irq*()") platform_get_irq() produces an error message
orion-mdio f1072004.mdio: IRQ index 0 not found
which is perfectly normal if one hasn't specified the optional property
in the device tree.
