Re: [linux-uvc-devel] [PATCH v3] uvcvideo: uvc_scan_fallback() for webcams with broken chain

[infernix <inf...@in...>]

Hi,

This patch also fixes "No valid video chain found" for 0bda:5751 
(Realtek) which is the front-facing camera in Dell Venue 11 Pro tablets.

Any chance of merging this upstream?

Thanks!
