Also wrong, you removed the creation of the links in sysfs.
that's not good..
The assignment to nowarn was there to avoid another compiler warning,
as sysfs_create_link() is marked __must_check.

alright.. thanks for having a look
and a response. if somebody has a fix
for this then let me know, and I can
test it out over here(I can also try
fixing this as well, but my knowledge
of code only goes so far)..
