I worked with Eilís Ní Fhlannagáin on social media who has also confirmed this to solve
her camera issue with her Dell XPS 13 (I didn't get the specific model).

Took a looking at linux-next today, I didn't see it. Anything else needed to get
this queued up?  We'd love to get this in the 4.18 merge window, and stable if
possible.
