Subject: [PATCH] watchdog: bcm_kona_wdt: Use correct return value for bcm_kona_wdt_probe()
Date: Mon, 25 May 2020 15:31:04 +0800 [thread overview]
Message-ID: <1590391864-308-1-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.
