From ae3696c167cc04d32634c4af82f43b446c5176b0 Mon Sep 17 00:00:00 2001 From: Alexandre Belloni Date: Wed, 26 Apr 2017 12:06:28 +0200 Subject: net: macb: fix phy interrupt parsing Since 83a77e9ec415, the phydev irq is explicitly set to PHY_POLL when there is no pdata. It doesn't work on DT enabled platforms because the phydev irq is already set by libphy before. Fixes: 83a77e9ec415 ("net: macb: Added PCI wrapper for Platform Driver.")
