Good point(s).  Please try to use Documentation/SubmitChecklist,
as indicated in Andrew's -mm announcements (and copied in my sig below).

Hi!

> BUilding with sparse shows lots of warnings.

You seem to be the lucky one, able to actually compile the
beast. Could you run diff against vanilla and post it somewhere?

"Normal" installation procedure has too many steps in my eyes, and
combined git tree is not available, so I was waiting for merge at
least into -wirelessdev tree.

"make patch_kernel" would patch the kernel from wireless-dev.git.  If
the Linux source tree is not configured, just run "make distclean" after
that (or apply my patch from the previous post in the ipw3945-devel
list).

You can use StGIT for convert the changes made by "make patch_kernel" to
a local patch so that updating from the upstream git repository is still
possible with "stg pull".

No need to wait for anything.
