Oh, I missed these 2 extra occurrences. My bad, with defconfig everything
compiles fine.
Johannes, could you please replace patch with following? I appended to the patch,
it is better then having 2 patches with broken compilation in between.

Subject: [PATCH v2] cfg80211: remove @gfp parameter from cfg80211_rx_mgmt()
To: Johannes Berg <johannes@sipsolutions.net>
Cc: linux-wireless@vger.kernel.org,
Vladimir Kondratiev <qca_vkondrat@qca.qualcomm.com>
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.
