Subject: [PATCH] ASoC: qcom: qdsp6: Use IS_ERR() instead of IS_ERR_OR_NULL()
Date:   Tue, 14 Jul 2020 19:27:44 +0800
Message-Id: <20200714112744.20560-1-tangbin@cmss.chinamobile.com>
MIME-Version: 1.0

Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

In the function q6adm_open(), q6adm_alloc_copp() doesn't return 
NULL. Thus use IS_ERR() to validate the returned value instead 
of IS_ERR_OR_NULL(). And delete the extra line.
