The fix is correct and well-placed. `anx7625_typec_set_status()` is the function that dispatches to `anx7625_typec_set_orientation()` and the data/power role status paths, all of which ultimately call `typec_set_*()` functions that will dereference the port pointer. Guarding at this single entry point covers all downstream call sites.

One question: the changelog notes that a chunk fixing `anx7625_typec_unregister()` was dropped. Does `anx7625_typec_unregister()` also need a NULL guard on `ctx->typec_port` before calling `typec_unregister_port()`? If the driver's remove/unbind path can be reached without the typec port having been successfully registered (e.g., probe succeeded but typec registration was skipped because the connector fwnode was absent), then the same NULL dereference would occur on driver removal. It would be worth confirming that the unregister path is already safe.

Otherwise, no issues found. The fix is minimal, targeted, has the correct Fixes: tag, and the commit message clearly explains the problem with an actual crash trace.
