| 4 | Subject: [PATCH] net: mvmdio: avoid error message for optional IRQ |
| 5 | |
| 6 | Per the dt-binding the interrupt is optional so use |
| 7 | platform_get_irq_optional() instead of platform_get_irq(). Since |
| 8 | commit 7723f4c5ecdb ("driver core: platform: Add an error message to |
| 9 | platform_get_irq*()") platform_get_irq() produces an error message |
| 10 | |
| 11 | orion-mdio f1072004.mdio: IRQ index 0 not found |
| 12 | |
| 13 | which is perfectly normal if one hasn't specified the optional property |
| 14 | in the device tree. |
