From 970fdfa89babb5a6f1a3d345e8cb54d92c1e3a8f Mon Sep 17 00:00:00 2001 From: Vladimir Kondratiev Date: Mon, 11 Aug 2014 03:29:57 -0700 Subject: cfg80211: remove @gfp parameter from cfg80211_rx_mgmt() In the cfg80211_rx_mgmt(), parameter @gfp was used for the memory allocation. But, memory get allocated under spin_lock_bh(), this implies atomic context. So, one can't use GFP_KERNEL, only variants with no __GFP_WAIT. Actually, in all occurrences GFP_ATOMIC is used (wil6210 use GFP_KERNEL by mistake), and it should be this way or warning triggered in the memory allocation code. Remove @gfp parameter as no actual choice exist, and use hard coded GFP_ATOMIC for memory allocation.
