There was no such change just a discussion of what the kernel has been doing since 2.5.8 or so.

There is a bug in device_suspend. device_shutdown, and device_suspend where merged and the POWER_DOWN case now removes the drivers which is a bug. You may be getting hit with that.
Eric Blade has posed a patch fixing that.
Or else there is a change in the ->remove() method of one your drivers.
