Subject: [PATCH 1/2] rtc:rtc-digicolor: Use PTR_ERR_OR_ZERO to replace the open code
Date:   Mon, 13 Aug 2018 19:31:24 +0800
Message-ID: <1534159885-25364-2-git-send-email-zhongjiang@huawei.com>

Precedence: bulk

PTR_ERR_OR_ZERO has implemented the if(IS_ERR(...)) + PTR_ERR, So
just replace them rather than duplicating its implement.
