Subject: [PATCH] stmmac: Fix phy without MDIO subnode
Date: Thu, 24 Mar 2016 10:56:52 +0000	[thread overview]
Message-ID: <1458817012-14293-1-git-send-email-john@metanate.com> (raw)

Since commit 88f8b1bb41c6 ("stmmac: Fix 'eth0: No PHY found'
regression") we no longer allocate mdio_bus_data unless there is a MDIO
subnode.  This breaks the ethernet on the Radxa Rock2 (using
rk3288-rock2-square.dts) which does not have an MDIO subnode.

That commit was correct that the phy_bus_name test is unhelpful since we
allocate "plat" in the same function and never set phy_bus_name so let's
just drop the test which restores the previous behaviour.

Fixes: 88f8b1bb41c6 ("stmmac: Fix 'eth0: No PHY found' regression")
