I don't really think that device_shutodwn() belongs in base/power/.

Moving it to a separate file sounds like a good idea, but let that file
reside in base/ proper.

Then, I would separate the dpm_list definition, locking etc out of
base/power/, move it to the new file containing device_shutdown() and
make the code in base/power/ refer to it (you may want to move the list
entry list head from dev_pm_info to struct device directly while at that
too).

Then, it should be straightforward enough to switch device_shutdown() over to
using it.

Thanks,
