Who needs this?

Why is this in the patchset? What are the dependencies? Please clearly express dependencies between patches or merging needs in cover letter. Otherwise please do not combine unrelated patches from different subsystems together. It's make review and merging only difficult.

Why? How is this related to the goal "add a helper"? Where is the helper used? I don't see. Don't combine unrelated topics in one patch.

Why are you duplicating w1_search_master_id()? Without locking? Sorry, this looks like you did not look at all at existing code.
