From 6cb7ea1426208ebfcc57f6fae654d1c25e89f7fe Mon Sep 17 00:00:00 2001 From: Yushan Zhou Date: Mon, 7 Nov 2022 17:25:44 +0800 Subject: rtc: rzn1: Check return value in rzn1_rtc_probe [ Upstream commit 9800f24f7bd5b99fb4fc4ce981427102e2e15a1c ] The rzn1_rtc_probe() function utilizes devm_pm_runtime_enable() but wasn't checking the return value. Fix it by adding missing check.
