Beats me :-( Is it systematic or pseudo-random?

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.
