[1/3] net/can: use module_pci_driver

This patch converts the drivers in drivers/net/can/* to use
module_pci_driver() macro which makes the code smaller and a bit simpler.

Hello Dave,

i've seen that you applied the two pci simplifications from Axel Lin to the
net-next tree

http://patchwork.ozlabs.org/patch/152473/
http://patchwork.ozlabs.org/patch/152474/

... but only this one is marked 'awaiting upstream' ?

http://patchwork.ozlabs.org/patch/152472/

What does this mean? Should Marc process this patch separately via his
can-next tree?

Regards,
Oliver
