From 52ea796b9161b1b81242e6831d9e128ee207ad2d Mon Sep 17 00:00:00 2001 From: Axel Lin Date: Mon, 23 Mar 2015 12:08:18 +0800 Subject: phy: qcom-ufs: Don't return error if fail to get optional resource "dev_ref_clk_ctrl_mem" is optional resource, so don't return error if fail to get the resource. Since it's an optional resource, don't emit error if fail to get dev_ref_clk_ctrl_mem. Also remove redundant test for res, it's done by devm_ioremap_resource().
