powerpc -next is a never-rebase branch, so we are somewhat stuffed here.
How do you suggest we proceed ? I can't add a fix to powerpc-next to use
the new function since it doesn't exist upstream yet. I would have to
pull drivers-core-next in which I really don't want to do....
Can the removal of the function be delayed to -rc1 so we can properly
do the fixup ? Or do you have the introduction of the new function in
a topic branch I can pull in without the rest of drivers-core-next ?
Cheers,
Ben.
