Subject: [PATCH v2] usb: core: phy: fix return value checking about devm_of_phy_get_by_index()
Date: Wed, 29 Aug 2018 10:10:48 +0800	[thread overview]
Message-ID: <8263a8d0f87d595dd35efa5432d294d9f7b38719.1535507412.git.chunfeng.yun@mediatek.com> (raw)

Use IS_ERR() instead of IS_ERR_OR_NULL() because devm_of_phy_get_by_index()
never return NULL value;
But still need ignore the error of -ENODEV, for more information, please
