From e1f550dc44a4d535da4e25ada1b0eaf8f3417929 Mon Sep 17 00:00:00 2001 From: Chris Packham Date: Thu, 12 Mar 2020 09:05:46 +1300 Subject: 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.
