Also wrong, you removed the creation of the links in sysfs.
The assignment to nowarn was there to avoid another compiler warning,
as sysfs_create_link() is marked __must_check.
I also went back to this one and made the following changes.. let me know if
it's wrong etc..

if it looks good, then I can resend it out.
Have you compile-tested this?
As sysfs_create_link() is marked __must_check, that will cause another compiler
warning, but only if CONFIG_SYSFS=y.
Perhaps you can just mark the nowarn variable __unused?
o.k. this builds cleanly without a warning, but is it the right thing
