Subject: [PATCH 3.17 02/25] net: systemport: fix bcm_sysport_insert_tsb()
Date: Mon, 13 Oct 2014 04:24:55 +0200	[thread overview]
Message-ID: <20141013022454.385617705@linuxfoundation.org> (raw)
In-Reply-To: <20141013022454.289398272@linuxfoundation.org>

3.17-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Florian Fainelli <f.fainelli@gmail.com>

[ Upstream commit e87474a6e697857df21cff0707a2472abceca8b3 ]

Similar to commit bc23333ba11fb7f959b7e87e121122f5a0fbbca8 ("net:
bcmgenet: fix bcmgenet_put_tx_csum()"), we need to return the skb
pointer in case we had to reallocate the SKB headroom.

Fixes: 80105befdb4b8 ("net: systemport: add Broadcom SYSTEMPORT Ethernet MAC driver")
