Message-ID: <1406026611-30493-22-git-send-email-kishon@ti.com> Date: Tue, 22 Jul 2014 16:26:44 +0530 From: Kishon Vijay Abraham I <kishon@...com> To: <gregkh@...uxfoundation.org> CC: <kishon@...com>, <linux-kernel@...r.kernel.org> Subject: [PATCH 21/28] 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.
