Subject: rt73usb WARNING: at net/mac80211/driver-ops.h:12 check_sdata_in_driver

Hi,

I've noticed that if I suspend to disk and then resume with my usb wifi
adapter plugged in I get a spew of these warnings from what looks to be
the wifi driver and some warning from the usb layer. Are these known issues?

rt73usb 1-2:1.0: no reset_resume for driver rt73usb?
