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.
