Subject: [PATCH 1/2] media: vicodec: constify v4l2_ctrl_ops structure
Date:   Sat, 27 Oct 2018 14:16:39 +0200
Message-Id: <1540642600-25840-2-git-send-email-Julia.Lawall@lip6.fr>
In-Reply-To: <1540642600-25840-1-git-send-email-Julia.Lawall@lip6.fr>
References: <1540642600-25840-1-git-send-email-Julia.Lawall@lip6.fr>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

The v4l2_ctrl_ops structure is only stored in the ops field of a
v4l2_ctrl_config structure, and this field is const, or passed as the
second argument of v4l2_ctrl_new_std, and the corresponding parameter
is declared as const.  Accordingly, the structure can also be const.

Done with the help of Coccinelle.
