[oe] [PATCH] fix acpid compiler warning on some platforms

[Christian Betz]

Thanks for the tip!

I will investigate getting this upstream. However, I may need some
guidance figuring out where upstream is.

acpid itself seems to be either extremely stable or unmaintained
(nothing in a very long time on the sourceforge page).
the patch in oe is simply called netlink.diff. Google lead me
here where you can download a tarball of a modified acpid-1.0.10:

 http://www.tedfelix.com/linux/acpid-netlink.html

however, no patches are provided.

there is a launchpad page which documents that ubuntu seems to be
creating patches from acpid-netlink

 https://launchpad.net/ubuntu/+source/acpid/1.0.10-4

My best guess is that upstream is actually acpid-netlink. I will try
to make contact.

The real question which involves deeper investigation is why oe
doesn't just pull directly from acpid-netlink (i.e. is netlink.diff
just cherry picked changes from acpid-netlink?). 

I never considered how difficult it can be to find upstream!
