From 2a4c37016ca96e413cd352985d3a0db8cfb7716c Mon Sep 17 00:00:00 2001 From: Kishon Vijay Abraham I Date: Mon, 14 Jul 2014 15:55:01 +0530 Subject: [PATCH] phy: core: Fix of_phy_provider_lookup to return PHY provider for sub node 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.
