These are caused by the fact that I moved the patch adding
class_compat_create_link() and friends out of the NEXT_PATCHES section.
I did so because Greg KH (Cc'd) added this patch to his driver-core
patch set, which I thought was part of linux-next. I simply didn't want
to apply the same patch twice.

To clarify the dependency, I added the following to my series.conf:

# NEXT_BASE driver-core.current

but apparently it didn't work as intended.

Greg, please clarify whether the patch in question
(driver-core-add-support-for-compatibility-classes.patch) is pushed to
linux-next or not.

Stephen, if my dependency tag is not correct, please tell me how to fix
it.

Thanks, and sorry for the trouble.
