| 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. |
