What? It's been in linux-next for a while now as it's been in my tree
for quite some time. Unless it somehow got reverted in -next and I
didn't realize it? Which I kind of doubt as it was causing problems
with the sparc build and I got reports of that.

This should be a simple merge, the show/store functions of sysdev now
just got an additional parameter, like we've done for a while with other
types of attributes.
