Subject: [PATCH 2/2] rtc: mpc5121: Use correct return value for mpc5121_rtc_probe()
Date: Mon, 25 May 2020 09:39:48 +0800 [thread overview]
Message-ID: <1590370788-15136-2-git-send-email-yangtiezhu@loongson.cn> (raw)
In-Reply-To: <1590370788-15136-1-git-send-email-yangtiezhu@loongson.cn>
When call function devm_platform_ioremap_resource(), we should use IS_ERR()
to check the return value and return PTR_ERR() if failed.
