- Replaced pr_notice with dev_err for proper kernel error logging.
- Added explicit cleanup of link->priv on failure in probe and config.
- Improved comments and readability in parport_probe() and parport_config().
- Ensured allocation checks are consistent (kzalloc returns checked).
- Minor refactoring for clarity and maintainability.
