[PATCH 4/6] [media] media: mt9m111: constify video_subdev structures

From: Julia Lawall
Date: Tue Aug 08 2017 - 07:24:11 EST


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.
