	See, I coded it up with PTR_ERR() first, and everyone I showed
it to said "I hate PTR_ERR()!".

	I wish you hadn't, because it won't be to difficult to go back
to PTR_ERR().  However, don't revert it - that affects some of the
follow-on patches that were affected by the change.
	I'll spin up a new PTR_ERR() change.  I have some more cleanups
coming too, they need to finish their time in linux-next.
