So the pages are marked as read-only. However, userspace will write to these buffers since it will fill in the data to output. Since get_userptr is only called if the userptr of the queued buffer has changed since the last time that same buffer was queued, this will fail when the buffer contents is updated and the buffer is queued again. E.g., userspace fills buffer 1 with the output video and queues it. The first time get_userptr is called and the pages are grabbed and pinned in memory and marked read-only. The second time buffer 1 is filled with different video data and queued again. Since the userptr hasn't changed the get_userptr() callback isn't called again. Since the pages were marked as read-only the new contents isn't updated. Just always call vb2_create_framevec() with FOLL_WRITE to always allow writing to the buffers. Using USERPTR streaming with OUTPUT devices is almost never done. And when it is done it is via v4l2-compliance and a driver like vim2m. But since v4l2-compliance doesn't actually inspect the capture buffer and compare it to the original output buffer, this issue was never noticed. But the vicodec driver actually needs to parse the bitstream in the OUTPUT buffers and any errors there will be immediately noticed. So this time v4l2-compliance failed the USERPTR streaming test.

On platforms where the sensor is instantiated from a DT (MMP2) it is going to happen asynchronously. Therefore, the current modus operandi, where the bridge driver fiddles with the sensor power and clock itself is not going to fly. As the comments wisely note, this doesn't even belong there. Luckily, the ov7670 driver is already able to control its power and reset lines, we can just drop the MMP platform glue altogether. It also requests the clock via the standard clock subsystem. Good -- let's set up a clock instance so that the sensor can ask us to enable the clock. Note that this is pretty dumb at the moment: the clock is hardwired to a particular frequency and parent. It was always the case.

However, those callbacks are also used by drivers, e.g., V4L2 host interfaces. Since both subdev_do_ioctl() and drivers are using v4l2_subdev_call() macro while calling subdevice operations, move those parameter checks from subdev_do_ioctl() to v4l2_subdev_call() so we can avoid taking care of those checks inside drivers. Define a wrapper function for each operation callback in scope, then gather those wrappers in a static v4l2_subdev_ops structure so the v4l2_subdev_call() macro can find them easy if provided.

In a later patch this will be moved to uapi/linux/cec.h. The CEC_CAP_CONNECTOR_INFO capability can be set by drivers, but cec_allocate_adapter() will remove it again until the public API for this can be enabled once all drm drivers wire this up correctly. Also add the cec_fill_conn_info_from_drm and cec_s_conn_info functions, which are needed by drm drivers to fill in the cec_connector info based on a drm_connector. The cec_notifier_(un)register and cec_register_cec_notifier prototypes were moved from cec-notifier.h to cec.h since cec.h no longer includes cec-notifier.h. These headers included each other before, which caused various problems. Due to these changes the seco-cec driver was changed as well: it should include cec-notifier.h, not cec.h.

This replaces cec_notifier_get_conn/cec_notifier_put. For CEC adapters it is also no longer needed to call cec_notifier_register, cec_register_cec_notifier and cec_notifier_unregister. This is now all handled internally by the new functions.
