Subject: [PATCH 1/2] phy: rockchip: Fix return value of inno_dsidphy_probe()
Date: Mon, 25 May 2020 12:08:58 +0800	[thread overview]
Message-ID: <1590379739-18729-1-git-send-email-yangtiezhu@loongson.cn> (raw)

When call function devm_platform_ioremap_resource(), we should use IS_ERR()
to check the return value and return PTR_ERR() if failed.
