Subject: [PATCH] rtc: rzn1: Check return value in rzn1_rtc_probe
Date: Mon,  7 Nov 2022 17:25:44 +0800	[thread overview]
Message-ID: <20221107092544.3721053-1-zys.zljxml@gmail.com> (raw)

From: Yushan Zhou <katrinzhou@tencent.com>

The rzn1_rtc_probe() function utilizes devm_pm_runtime_enable()
but wasn't checking the return value. Fix it by adding missing
check.

Fixes: deeb4b5393e1 ("rtc: rzn1: Add new RTC driver")
