Subject: [PATCH v2] drm/stm: check pitch and size calculations even if !CONFIG_MMU
Date:   Wed, 31 Jan 2018 09:05:08 +0100
Message-Id: <20180131080508.14356-1-benjamin.gaignard@linaro.org>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

In all cases we have to check pitch and size calculations to speed up
data transfer.

Fixes: 21f815bf773c ("drm/stm: drv: Improve data transfers")
