This reverts commit e878742c. Imgu should still keep the capability and flexibility to allow user to run 2 video pipes, as the user may use the video pipe to capture still frames with less system load and power than still pipe. Suggested-by:

This device does not function correctly in raw mode in kernel versions validating buffer sizes in bulk mode. It erroneously announces 16 bits per pixel instead of 12 for NV12 format, so it needs this quirk to fix computed frame size and avoid legitimate frames getting discarded.

This causes the 'struct uvc_entity' representing the display to be added to its chain list twice during 'uvc_scan_chain()': once via 'uvc_scan_chain_entity()' when it is processed directly from the 'dev->entities' list and then again immediately afterwards when trying to follow the source ID in 'uvc_scan_chain_forward()' Add a check before adding an entity to a chain list to ensure that the entity is not already part of a chain.

Make sure to use the current alternate setting, which need not be the first one by index, when verifying the endpoint descriptors and initialising the URBs. Failing to do so could cause the driver to misbehave or trigger a WARN() in usb_submit_urb() that kernels with panic_on_warn set would choke on.

Despite using M2M in both the decoder and encoder, this driver used vb2_v4l2_buffer as its base buffer structure, and placed a list_head right after the buffer declaration in order to match the layout of a v4l2_m2m_buffer. This is very dangerous as it means the driver will break should the layout of v4l2_m2m_buffer change. Fix this by directly using v4l2_m2m_buffer and updating the sites that accessed the buffer accordingly. Signed-off-by:
