+Patch fixes warnings like below happened on resume:
+
+WARNING: at net/mac80211/driver-ops.h:12 check_sdata_in_driver+0x32/0x34()
+
+Problem is that in __ieee80211_susped() we remove sdata (i.e wlan0
+interface) and then during resume we call usb_unbind_interface() ->
+ieee80211_unregister_hw() with sdata removed.
+
+Patch fixes problem by adding .reset_resume calback, hence we do not
+unbind usb device on resume. This callback can be the same as normal
+.resume callback, sice we do all needed initalization during interface
+start, which is performed on resume [ ieee80211_resume() ->
+ieee80211_reconfig() -> rt2x00mac_start() -> rt2x00lib_start ].
