Hi Hans,

The v4l2_ctrl_new_std() doesn't allow setting the is_volatile bit in the
bit field. The adp1653 driver needs that for the faults control.

Would you prefer just setting the bit in the driver, or, as Laurent
suggested, a new v4l2_ctrl_new_std_volatile() function which would mark
the control as volatile by itself?

Regards,

Just set the bit in the driver.

If this will start happening a lot, then we can consider adding a special
function for this, but volatile controls are still pretty rare and I do
not think it warrants a special function just for that.
