An issue was discovered in the max7301 crate before 0.2.0 for Rust. The ImmediateIO and TransactionalIO types implement Sync for all Expander<EI> types that they contain.

GHSA-rmff-f8w9-c9rm — Data races in max7301

Affected: crates.io: max7301

The `ImmediateIO` and `TransactionalIO` types implement `Sync` for all contained `Expander<EI>` types regardless of if the `Expander` itself is safe to use across threads.

As the `IO` types allow retrieving the `Expander`, this can lead to non-thread safe types being sent across threads as part of the `Expander` leading to data races.
