From cf104c2a207f550d9c3b8f8bcf73cb11765692f6 Mon Sep 17 00:00:00 2001 From: Kalle Valo Date: Thu, 21 Jul 2011 10:04:54 +0300 Subject: [PATCH] ath6kl: fix atomicity in ath6kl_cfg80211_scan_node() ath6kl_cfg80211_scan_node() was calling cfg80211_inform_bss_frame() with CFP_KERNEL but the function is executed with a spin lock taken. This is wrong and the function must use GFP_ATOMIC instead.
