Drop the "Video, VBI and RDS Looping" section, instead moving the Video/VBI info to section "Video and Sliced VBI looping" and the RDS info to section "Radio & RDS Looping". Signed-off-by:Hans Verkuil <hverkuil-cisco@xs4all.nl>

The documentation contained several instances of "section X" references, which no longer map to whatever X was. Replace these by the section titles. Also fix a single confusing typo in the "Radio & RDS Looping" section: "are regular frequency intervals" -> "at regular frequency intervals" Signed-off-by:

This reverts commit 77d32b7e. This patch is obviously wrong (causes array accesses at index -1), and I caught that just too late.

To support sources that implement the .enable_streams() and .disable_streams() operations, replace the manual calls to the subdev .s_stream() operation with the v4l2_subdev_enable_streams() and v4l2_subdev_disable_streams() helpers. The helpers fall back to .s_stream() if the source doesn't implement the new operations, so backward compatibility is preserved. Signed-off-by:

Store the active formats and crop rectangle in the subdevice active state. This simplifies implementation of the format and selection accessors, and allows using the v4l2_subdev_get_fmt() helper to implement the .get_fmt() operation. The active configuration that is used in the .process_frame() handler is still stored in the vimc_scaler_device structure. The driver could instead access the active state in the .process_frame() handler, but the required locking could interfere with the real time constraints of the frame processing. This data would be stored in registers in the .s_stream() handler for real hardware, storing it in dedicated storage thus mimics a real driver. To differentiate them from the rest of the device private data, move the corresponding fields to a sub-structure of vimc_scaler_device named hw. Signed-off-by:

smatch generated this warning: drivers/media/usb/b2c2/flexcop-usb.c:199 flexcop_usb_memory_req() warn: iterator 'i' not incremented and indeed the function is not using i or updating buf. The reason this always worked is that this function is called to write just 6 bytes (a MAC address) to the USB device, and so in practice there is only a single chunk written. If we ever would need to write more than one chunk, this function would fail since each chunk would read from or write to the same buf address. Rewrite the function to properly handle this.
