====================
pull-request: can-next 2015-04-01
this is a pull request of 5 patches for net-next/master.
There are two patches for the ems_usb driver by Gerhard Uttenthaler and
me, which fix sparse endianess warnings. Oliver Hartkopp adds two
patches to improve and extend the CAN-ID filter handling on RAW CAN
sockets. The last patch is by me, it silences an uninitialized variable
warning in the peak_usb driver.
