Alex, this is broken when the sysfs interface isn't enabled. Can you
send a fixup patch?

[PATCH] gpiolib: fix link error when sysfs is not built

[Alexandre Courbot]

From: Alexandre Courbot <acourbot@nvidia.com>

Fix all compilation errors and warnings triggered by my latest series of
patch on Grant's linux-next branch. Please meld this patch into the culprit
one to avoid ending with a commit that breaks compilation in the git history.

Applied, thanks. I've pushed it out as a separate commit since I had
already pushed my tree out. so I need to make sure linusw hasn't pulled
it and applied anything on top before I respin.

Sorry about that. I have sent you the fix in a separate mail. Please 
meld it into the culprit commit to fix this.

Thanks,
