Actually, I take that back. I did a clang build, and clang noted that
my "remove the retval initialization as unnecessary" was wrong,
because the

                if (!bprm->fdpath)
                        goto out_free;

code path in alloc_bprm() still wanted that initial -ENOMEM initialization.

So you need to fix the

        int retval;

in alloc_bprm() to be back to the original

        int retval = -ENOMEM;

but then it might all work.

Again - note the "might". Somebody needs to actually test it.  I may
try to do that in between pulls.
