I think this patch is being built with the wrong git tree. The new
types for these three errors landed in sre's linux-power-supply here :
https://git.kernel.org/cgit/linux/kernel/git/sre/linux-power-supply.git/commit/?h=next&id=6659b55dae09b2042d8cdd0f4576502c3e81957c

It should be in most recent linux-nexts, but it wouldn't be in v4.5-rc7.
