v4l2_fwnode_endpoint_parse() and v4l2_fwnode_endpoint_alloc_parse() take
a fwnode as the first argument and leave it up to the caller to check a
valid fwnode has been obtained through various means. Instead, add a check
here so the callers won't need to do that anymore.

The vast majority of the callers of v4l2_ctrl_new_fwnode_properties() do
check the returned error code but the function does not set the control
handler's error on failure. This will make error handling more complicated
and prone for bugs.

Always assign the control handler's error field on error in
v4l2_ctrl_new_fwnode_properties().

Adding a reference count to the v4l2_m2m_dev structure allow safely
sharing it across multiple hardware nodes. This can be used to prevent
running jobs concurrently on m2m cores that have some internal resource
sharing.

[hverkuil: fix typos in v4l2_m2m_put documentation]

Keep track of the number of requests and request objects of a media
device. Helps to verify that all request-related memory is freed.

By default when the last request object is completed, the whole
request completes as well.

But sometimes you want to delay this completion to an arbitrary point in
time so add a manual complete mode for this.

In req_queue the driver marks the request for manual completion by
calling media_request_mark_manual_completion, and when the driver
wants to manually complete the request it calls
media_request_manual_complete().

The media kAPI has two global variables at v4l2-ioctl.h. Document

Drop the wait_prepare/finish callbacks. Instead require that the vb2_queue
lock field is always set and use that lock when waiting for buffers to
arrive.

Since vb2 now relies on the presence of the vb2_queue lock
field and there are no more drivers that use these helpers, it is safe
to drop them.

Since commit 88785982a19d ("media: vb2: use lock if wait_prepare/finish
are NULL") it is no longer needed to set the wait_prepare/finish
vb2_ops callbacks as long as the lock field in vb2_queue is set.

Set the queue lock to &ctx->mutex, which makes it possible to drop
the wait_prepare/finish callbacks.

This simplifies the code and this is a step towards the goal of deleting
these callbacks.
