From: Julia Lawall Date: Tue, 8 Aug 2017 10:58:27 +0000 (-0400) Subject: media: v4l: mt9t001: constify video_subdev structures X-Git-Tag: v4.14-rc6~35^2~255 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=a828d818bf6f48e1f594a19df0594af9065dc5dc;p=platform%2Fkernel%2Flinux-rpi.git media: v4l: mt9t001: constify video_subdev structures 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.
