Resend of the patch originally posted on 2026-05-04 [1], which has
received no maintainer feedback for ~6 weeks. No functional changes;
only rebased onto the current bluetooth-next (the quirks_table layout
shifted in the meantime). CI passed on the original posting
(CheckPatch/BuildKernel/Sparse, patchwork series 1089463).
