Browse Source 
These are no longer used (finally!), so remove them.

@ -96,21 +96,6 @@ Basic usage for V4L2 and sub-device drivers
Where foo->sd is of type struct v4l2_subdev.
And set all core control ops in your struct v4l2_subdev_core_ops to these
helpers:
.queryctrl = v4l2_subdev_queryctrl,
.querymenu = v4l2_subdev_querymenu,
.g_ctrl = v4l2_subdev_g_ctrl,
.s_ctrl = v4l2_subdev_s_ctrl,
.g_ext_ctrls = v4l2_subdev_g_ext_ctrls,
.try_ext_ctrls = v4l2_subdev_try_ext_ctrls,
.s_ext_ctrls = v4l2_subdev_s_ext_ctrls,
Note: this is a temporary solution only. Once all V4L2 drivers that depend
on subdev drivers are converted to the control framework these helpers will
no longer be needed.
1.4) Clean up the handler at the end:
v4l2_ctrl_handler_free(&foo->ctrl_handler);
