From c752cac9db1b0c469db7ba9d17af4ba708984db5 Mon Sep 17 00:00:00 2001 From: Yan-Hsuan Chuang Date: Tue, 23 Oct 2018 11:24:44 +0800 Subject: mac80211: fix GFP_KERNEL under tasklet context cfg80211_sta_opmode_change_notify needs a gfp_t flag to hint the nl80211 stack when allocating new skb, but it is called under tasklet context here with GFP_KERNEL and kernel will yield a warning about it.
