Subject: [media] v4l2-subdev.h: add g_tvnorms video op
Author:  Hans Verkuil <[email protected]>
Date:    Mon Feb 17 08:44:12 2014 -0300

While there was already a g_tvnorms_output video op, it's counterpart for
video capture was missing. Add it.

This is necessary for generic bridge drivers like soc-camera to set the
video_device tvnorms field correctly. Otherwise ENUMSTD cannot work.
