In com_banners clients the dropdown select has both Name and Client ordering
In this view the column heading is Client not Name
If you try the ordering then you will see that the Name ordering sorts by the Client column and the Client ordering does nothing
Apply this patch and You only have Client ordering which works
I have tested this item successfully on 6c45ff5
Test OK
