+ ath9k: fix race in setting ATH_OP_INVALID
+
+ The commit "ath9k: move sc_flags to ath_common" moved setting
+ ATH_OP_INVALID flag below ieee80211_register_hw. This is causing
+ the flag never being cleared randomly as the drv_start is called
+ prior to setting flag. Fix this by setting the flag prior to
+ register_hw.
