In the past, only string controls were pointers. That changed when compounded types got added, but the compat32 code was not updated.
We could just add those controls there, but maintaining it is flaw, as we often forget about the compat code. So, instead, rely on the control type, as this is always updated when new controls are added. As both v4l2-ctrl and compat32 code are at videodev.ko module, we can move the ctrl_is_pointer() helper function to v4l2-ctrl.c. --- Re-sending this patch series, as it was c/c to the linux-doc ML by mistake.
