Merge tag 'linux-can-next-for-4.4-20151013' of git://git.kernel.org/pub/scm/linux/kernel/git/mkl/linux-can-next
Marc Kleine-Budde says:
====================
pull-request: can-next 2015-09-17
this is a pull request of 4 patches for net-next/master.
Two patches are by Gerhard Bertelsmann, fixing some problems in the
sun4i driver. The patch by Arnd Bergmann stops using timeval for the
CAN broadcast manager. The last patch by Alexandre Belloni removes the
otherwise unused struct at91_can_data from the driver.
