Marc Kleine-Budde says:

====================
pull-request: can-next 2015-21-01

this is a pull request of 4 patches for net-next/master.

Andri Yngvason contributes one patch to further consolidate the CAN
state change handling. The next patch is by kbuild test robot/Fengguang
Wu which fixes a coccinelle warning in the CAN infrastructure. The two
last patches are by me, they remove a unused variable from the flexcan
and at91_can driver.
