From 13303c0fb1481e40377d072a29570e005e7bd032 Mon Sep 17 00:00:00 2001 From: Sara Sharon Date: Sun, 10 Apr 2016 15:51:54 +0300 Subject: iwlwifi: mvm: use helpers to get iwl_mvm_sta Getting the mvm station out of station id requires dereferencing the station id to get ieee80211_sta, then checking for pointer validity and only then extract mvm station out. Given that there are helpers to do it - use them instead of duplicating the code whenever we need only mvm station.
