this is a pull-request for net-next/master. There is are 9 patches by 
Fabio Baltieri and Kurt Van Dijck which add LED infrastructure and
support for CAN devices. Bernd Krumboeck adds a driver for the USB CAN
adapter from 8 devices. Oliver Hartkopp improves the CAN gateway
functionality. There are 4 patches by me, which clean up the CAN's
Kconfig.

Pulled, although:

1) You need to create an accessor helper for that can_skb_priv
   thing, every access to it is that horrible cast expression.

2) There is no reason to accomodate out of tree stuff, and for that
   reason I see no reason why you should need that headroom size
   check at all.

   Either the driver uses alloc_can_skb() or it does it's own SKB
   allocation and in-tree you've fixed that.

   You're just asking for trouble by trying to accomodate out of
   tree guys anyways, why if they create a headroom that happens
   to be the size of can_skb_priv.  See what a joke that test is?
   It's not really protecting fully against anything.

Thanks.
