* can: dev: Consolidate and unify state change handlingAndri Yngvason2014-12-07
| | | | | | | | | | | | | | | | | The handling of can error states is different between platforms. This is an attempt to correct that problem. I've moved this handling into a generic function for changing the error state. This ensures that error state changes are handled the same way everywhere (where this function is used). This new mechanism also adds reverse state transitioning in error frames, i.e. the user will be notified through the socket interface when the state goes down.

* can: unify identifiers to ensure unique include processingOliver Hartkopp2014-05-19
| | | | | | | | | | | | | Armin pointed me to the fact that the identifier which is used to ensure the unique include processing in lunux/include/uapi/linux/can.h is CAN_H. This clashed with his own source as includes from libraries and APIs should use an underscore '_' at the identifier start. This patch fixes the protection identifiers in all CAN relavant includes.

* can: add explicit copyrights to can headersUwe Kleine-König2013-09-21
| | | | | | | | | | | | These files are copied to the source code of user space applications (in this case can-utils) and so it makes sense to mention explicitly their copyright. I added the terms of C code that was introduced in the same commit as these headers.
