This device causes the system to wake up from suspend, as soon as it
enters it (even if the device attached to the receiver is powered off).
So, ignore remote wakeup events from it.

If this is a lightspeed receiver then it really should be handled by
hid-logitech-dj.c unless this new receiver is using a new protocol ?

I wonder if adding it there also fixes the remote
wakeup issue (I doubt it fixes it but worth a try) ?


Seems like the following series does indeed fix this issue:
