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.
