Subject: [PATCH 1/2] rtc: goldfish: Fix return value of goldfish_rtc_probe()
Date: Sat, 23 May 2020 17:56:21 +0800	[thread overview]
Message-ID: <1590227782-32249-1-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.

Fixes: 89576bebbc17 ("rtc: Use devm_platform_ioremap_resource()")
