ref-by: https://patches.linaro.org/project/linux-media/patch/20231213140450.21359-3-laurent.pinchart@ideasonboard.com/ The subdev .[gs]_frame_interval are video operations, but they operate on pads (and even on streams). Not only is this confusing, it causes practical issues for drivers as the operations don't receive a subdev state pointer, requiring manual state handling. To improve the situation, turn the operations into pad operations, and extend them to receive a state pointer like other pad operations. While at it, rename the operations to .[gs]et_frame_interval at the same time to match the naming scheme of other pad operations. This isn't strictly necessary, but given that all drivers using those operations need to be modified, handling the rename separately would generate more churn for very little gain (if at all).
