Subject: [PATCH 12/15] brcm80211: fmac: change allocation flag in brcmf_enq_event() function
Date: Thu, 9 Feb 2012 21:09:06 +0100 [thread overview]
Message-ID: <1328818149-4826-13-git-send-email-arend@broadcom.com> (raw)
In-Reply-To: <1328818149-4826-1-git-send-email-arend@broadcom.com>
As the function is called from atomic context it should not do the
kzalloc call with GFP_KERNEL.
