Can you make a follow-up patch that renames V4L2_IN/OUT_CAP_CUSTOM_TIMINGS to
V4L2_IN/OUT_CAP_DV_TIMINGS? The old name for this define is deprecated, so it
would be nice to fix this in this driver as well.

The code that adds the new define names went in just two days ago, so as far
as I am concerned there is no need to modify the patch again. A follow-up
patch is sufficient.

Regards,

	Hans
