Subject: [PATCH] drm/sun4i: use PTR_ERR_OR_ZERO macro.
Date:   Mon,  6 Jan 2020 17:00:52 +0300
Message-Id: <20200106140052.30747-1-wambui.karugax@gmail.com>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

Replace the use of IS_ERR and PTR_ZERO macros by returning the
PTR_ERR_OR_ZERO macro.
Changes suggested by coccinelle.
