To be honest, I do not remember how well we tested that error path way back when. Nevertheless gprs_detach() does basically the same thing, in the non-error case, and it definitely worked well as far as I could tell. Maybe Phonet should be dropped though. As much as I like to have my name in MAINTAINERS, I have not heard of any remaining users for up-to-date kernel versions. And with Broadcom shutting down what was Nokia Wireless Modems, I doubt we will see new users ever. -- Rémi Denis-Courmont -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
