Add a new vb2_qbuf_request() (a request-aware version of vb2_qbuf())
that request-aware drivers can call to queue a buffer into a request
instead of directly into the vb2 queue if relevent.
This function expects that drivers invoking it are using instances of
v4l2_request_entity and v4l2_request_e
Allow to specify a request to be used with the S_EXT_CTRLS and
G_EXT_CTRLS operations.

Add generic support for requests to the mem2mem framework. This just
requires calling vb2_qbuf_request() instead of vb2_qbuf() in

Hi everyone,
And thanks for all the feedback on the previous version! I have tried to
address as much as possible, which results in (another) almost rewrite. But I
think the behavior and structure are converging to something satisfying and
usable.
Besides the buffer queuing behavior that has b

Add a 'bool from_other_dev' argument: set to true if the two
handlers refer to different devices (e.g. it is true when
inheriting controls from a subdev into a main v4l2 bridge
driver).
This will be used later when implementing support for the
request API since we need to skip
