[PATCH 1/2] phy: core: Fix of_phy_provider_lookup to return PHY provider for sub node

From: Kishon Vijay Abraham I
Date: Mon Jul 14 2014 - 06:25:50 EST

Fixed of_phy_provider_lookup to return 'phy_provider' if _of_phy_get
passes the node pointer of the sub-node of phy provider node. This is
needed when phy provider implements multiple PHYs and each PHY is
modelled as the sub-node of PHY provider device node.
