uvcvideo: uvc_scan_fallback() for webcams with broken chain
From: Henrik Ingo <henrik.ingo@avoinelama.fi>
[ Upstream commit e950267ab802c8558f1100eafd4087fd039ad634 ]
Some devices have invalid baSourceID references, causing uvc_scan_chain()
to fail, but if we just take the entities we can find and put them
together in the most sensible chain we can think of, turns out they do
work anyway. Note: This heuristic assumes there is a single chain.
At the time of writing, devices known to have such a broken chain are
- Acer Integrated Camera (5986:055a)
- Realtek rtl157a7 (0bda:57a7)
