From c43933e61ea9b630521bf0d5cf06c155478308a7 Mon Sep 17 00:00:00 2001 From: Bing Zhao Date: Fri, 12 Apr 2013 10:34:18 -0700 Subject: [PATCH] mwifiex: remove redundant initialization for bss_descriptor Initialization of bss_descriptor is unnecessary as the entire structure will be overwritten by a memcpy followed by. Initialize disable_11ac flag properly by setting it to true in mwifiex_fill_new_bss_desc().
