Subject: [ 40/82] fec_mpc52xx: fix timestamp filtering

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

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

From: Stephan Gatzka <stephan@...zka.org>

commit 9ca3cc6f3026946ba655e863ca2096339e667639 upstream.

skb_defer_rx_timestamp was called with a freshly allocated skb but must
be called with rskb instead.
