__module_put_and_exit() is makred noreturn in module.h declaration, but is
lacking the attribute in the definition, which makes some tools (such as
sparse) unhappy. Amend the definition with the attribute as well (and
reformat the declaration so that it uses more common format).

Hi Jiri,
While I'm not sure we shouldn't just fix sparse, we should also
use __noreturn.
Cheers,
Rusty.

Oops, I applied it, and in testing noted that lguest had broken and
ended up getting distracted by that. I've acked it now (it will
probably wait until next merge window).
Thanks,
Rusty.

Sorry, non comprende :) Could you please elaborate? Are you saying this
patch broke lguest? What is the breakage about?

Not seeing this in your tree, let me send another friendly ping :)
Rusty, if you want me to take this through trivial.git, just let me know,
I'll happily do it.
