From a6501617e689ad80c4d185e0d8f485e0d0b1a708 Mon Sep 17 00:00:00 2001 From: Florian Fainelli Date: Mon, 18 Jul 2016 16:24:34 -0700 Subject: brcmfmac: Fix glob_skb leak in brcmf_sdiod_recv_chain commit 3bdae810721b33061d2e541bd78a70f86ca42af3 upstream. In case brcmf_sdiod_recv_chain() cannot complete a succeful call to brcmf_sdiod_buffrw, we would be leaking glom_skb and not free it as we should, fix this.
