Subject: [PATCH 2/4] misc: mic: Use PTR_ERR_OR_ZERO rather than its implementation
Date: Thu, 5 Sep 2019 14:43:13 +0800	[thread overview]
Message-ID: <1567665795-5901-3-git-send-email-zhongjiang@huawei.com> (raw)
In-Reply-To: <1567665795-5901-1-git-send-email-zhongjiang@huawei.com>

PTR_ERR_OR_ZERO contains if(IS_ERR(...)) + PTR_ERR. It is better to
use it directly. hence just replace it.
