Why are offloaded devices being suspended at all? Obviously, no
"sideband entity" can be using a suspended device, so it seems that:

- if the device is unused and meant to be suspended, sideband can be
  removed before suspending
- if the device becomes suspended while in use, obviously it's a bug
