Subject: [PATCH 1/2] media: ov7740: constify structures stored in fields of v4l2_subdev_ops structure
Date:   Sat, 27 Oct 2018 14:49:04 +0200
Message-Id: <1540644545-26184-2-git-send-email-Julia.Lawall@lip6.fr>
In-Reply-To: <1540644545-26184-1-git-send-email-Julia.Lawall@lip6.fr>
References: <1540644545-26184-1-git-send-email-Julia.Lawall@lip6.fr>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

The fields of a v4l2_subdev_ops structure are all const, so the
structures that are stored there and are not used elsewhere can be
const as well.

Done with the help of Coccinelle.
