The entire async suspend/resume patchset is targeted at .33, so this is all
fine.

Subject: PM: Allow serio input devices to suspend/resume asynchronously

Set async_suspend for all serio input devices, so that they can be
suspended and resumed asynchronously with other devices they don't
depend on in a known way (i.e. devices which are not their parents
or children and to which they are not connected via struct pm_link
objects).
