Subject: [PATCH] drm/panel: remove meaningless if(ret) check code.
Date:   Wed, 22 Jul 2020 09:41:07 +0800
Message-Id: <20200722014107.26045-1-bernard@vivo.com>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

The function drm_panel_add always returns true.
So if(ret) check code will never run into error branch.
Remove these check make the code a bit readable.
