sbs-manager has been added to linux-next through the i2c tree due to
dependencies, so this one also needs to go through i2c.

I want to send Linus my pull request early this time (like today or
tomorrow). So, you either apply this patch then yourself afterwards on
top of linus' tree. Or I send it to him, but then I'd need the original
patch bounced or resent. Both fine with me.
