From da290c54610f49ef475f7f88668259216b08fc36 Mon Sep 17 00:00:00 2001 From: Jes Sorensen Date: Tue, 15 Apr 2014 19:43:52 +0200 Subject: [PATCH] staging: rtl8723au: OnAssocReq23a(): Clean up and use more ieee80211.h This converts it to use struct ieee80211_mgmt and cfg80211_find_ie(). In addition fix a potential buffer overrun in the last loop searching through list WLAN_EID_VENDOR_SPECIFIC elements.
