Isn't a clean revert - build dies with:

  CC      net/mac80211/scan.o
net/mac80211/scan.c: In function 'ieee80211_scan_state_decision':
net/mac80211/scan.c:510: error: implicit declaration of function 'pm_qos_request'
make[1]: *** [net/mac80211/scan.o] Error 1
make: *** [net/mac80211/scan.o] Error 2

Will investigate more later, find what other commit needs reverting.
