There was a problem hiding this comment.
This is a good change, but it should be in its own pull request. It also should have a better explanation in the commit message, and a comment explaining what the function actually returns.
Suggestion for commit message:
Make rproc_virtio_negotiate_features() return the mask of features successfully negotiated.
The comment for rproc_virtio_negotiate_features () could be worded similarly.
