====================
pull-request: can-next 2015-03-23

this is a pull request of 6 patches for net-next/master.

A patch by Florian Westphal, converts the skb->destructor to use
sock_efree() instead of own destructor. Ahmed S. Darwish's patch
converts the kvaser_usb driver to use unregister_candev(). A patch by
me removes a return from a void function in the m_can driver. Yegor
Yefremov contributes a patch for combined rx/tx LED trigger support. A
sparse warning in the esd_usb2 driver was fixes by Thomas Körper. Ben
Dooks converts the at91_can driver to use endian agnostic IO accessors.
