Merge branch 'for-davem' of git://gitorious.org/linux-can/linux-can-next

Marc Kleine-Budde says:

====================
this is pull request is for net-next. Contains a patch by Andreas
Larsson, which enables the sja1000 of driver to work under sparc.
AnilKumar Ch contributed a patch to improve the c_can support under
omap, Olivier Sobrie's patch brings support for the CAN/USB dongles
from Kvaser. In a bunch of patches by me missing MODULE_ALIAS and/or
MODULE_DEVICE_TABLE entries were added to the CAN drivers.
