Subject: [PATCH] drm/msm/dpu: fix wrong return value in dpu_encoder_init()
Date:   Wed,  1 Jul 2020 12:11:39 +0800
Message-Id: <20200701041139.92191-1-tianjia.zhang@linux.alibaba.com>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

A positive value ENOMEM is returned here. I thinr this is a typo error.
It is necessary to return a negative error value.
