Hi Greg,
I viewed 3.12-rc4 and IMHO it still has this issue, Please correct me if I'm wrong.
This patch was based on 3.12-rc4, following is version info of my code base:

linux/Makefile:
VERSION = 3
PATCHLEVEL = 12
SUBLEVEL = 0
EXTRAVERSION = -rc4

And this version of patch has one line not correct, I updated it in another mail 
with title "[PATCH v2]n_gsm:...", would you please check?

thanks a lot,
chao
