2017-08-20media: v4l: mt9t001: constify video_subdev structuresJulia Lawall
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.

2017-08-20media: ov5670: Fix incorrect frame timing reported to userChiranjeevi Rapolu
Previously, pixel-rate/(pixels-per-line * lines-per-frame) was yielding incorrect frame timing for the user. OV sensor is using internal timing and this requires conversion (internal timing -> PPL) for correct HBLANK calculation. Now, change pixels-per-line domain from internal sensor clock to pixels domain. Set HBLANK read-only because fixed PPL is used for all resolutions. And, use more accurate link-frequency 422.4MHz instead of rounding down to 420MHz.
