====================
pull-request: can 2015-11-23

this is a pull request of three patches for the upcoming v4.4 release.

The first patch is by Mirza Krak, it fixes a problem with the sja1000 driver
after resuming from suspend to disk, by clearing all outstanding interrupts.
Oliver Hartkopp contributes two patches targeting almost all driver, they fix
the assignment of the error location in CAN error messages.
