I believe we have decided here we will move into this direction.

So instead of using this 'lock_vol()' constants  - we will switch into

function calls - so the setting flags will disappear from generally used
header file and will be private to .c implementation.

I think this 'cleanup' patch is rather going in opposite direction ?
