I grepped for the adv7180 and it seem that I'm the only user of the adv7180 (sta2x11 VIP driver). In the VIP driver I don't use the control framework (there aren't controls), so I think these lines must be there. Am I wrong? Correct. But once sta2x11 is converted to using the control framework, then these lines can be dropped since no one else is using this subdevice driver. What do you suggest? I re-submit this patch and when sta2x11 is fixed a I submit a new patch to remove these lines; or wait the full conversion of the sta2x11 driver and submit both patch? Choice 1: when sta2x11 is fixed submit a new patch to remove those lines.
