I'd like the vendor.h change in a separate commit

The changes to files in different directories should be separated 
whenever possible.  See 'HACKING' document in the top level directory of 
the source tree, particularly the 'Submitting Patches' section.

So your commits should be:
vendor.h change
gprs-context.c change
sim900.c change

You're mixing tabs and spaces for indentation all over here.  We only 
use tabs.

Again, tabs for indentation only please
