As I and IIRC someone else pointed out there is an error code encoded in
the pointer if IS_ERR() is true, we should use that error code.

Please submit patches using subject lines reflecting the style for the
subsystem, this makes it easier for people to identify relevant patches.
Look at what existing commits in the area you're changing are doing and
make sure your subject lines visually resemble what they're doing.
There's no need to resubmit to fix this alone.
