Subject: [PATCH 4/6] [media] media: mt9m111: constify video_subdev structures
Date: Tue,  8 Aug 2017 12:58:30 +0200	[thread overview]
Message-ID: <1502189912-28794-5-git-send-email-Julia.Lawall@lip6.fr> (raw)
In-Reply-To: <1502189912-28794-1-git-send-email-Julia.Lawall@lip6.fr>

The v4l2_subdev_ops structure is only passed as the third argument
of v4l2_i2c_subdev_init, which is const, so the v4l2_subdev_ops
structure can be const as well.  The other structures are only
stored in the v4l2_subdev_ops structure, all the fields of which are
const, so these structures can also be const.

Done with the help of Coccinelle.
