Purpose

Before this change, any deployment of an MoE kernel that isn't setup to use DP would print a warning about this even if DP wasn't being used at all. I just want to restrict this to only trigger if DP is used.

👋 Hi! Thank you for contributing to the vLLM project.

💬 Join our developer Slack at https://slack.vllm.ai to discuss your PR in #pr-reviews, coordinate on features in #feat- channels, or join special interest groups in #sig- channels.

Just a reminder: PRs would not trigger full CI run by default. Instead, it would only run fastcheck CI which starts running only a small and essential subset of CI tests to quickly catch errors. You can run other CI tests on top of those by going to your fastcheck build on Buildkite UI (linked in the PR checks section) and unblock them. If you do not have permission to unblock, ping simon-mo or khluu to add you in our Buildkite org.

Once the PR is approved and ready to go, your PR reviewer(s) can run CI to test the changes comprehensively before merging.

To run CI, PR reviewers can either: Add ready label to the PR or enable auto-merge.

Code Review

This pull request introduces a small but useful cleanup in the Fused MoE configuration. The change ensures that a warning about MoE Data Parallelism (DP) setup is only logged when DP is actually enabled (dp_size > 1). This prevents unnecessary warnings and reduces log noise when DP is not in use. The implementation is correct and straightforward. I have no further comments.
