3.13.11.6 -stable review patch. If anyone has any objections, please let me know.
------------------ From: George Cherian <[email protected]> commit 33cf75656923ff11d67a937a4f8e9344f58cea77 upstream. The raminit register is shared register for both can0 and can1. Since commit: 32766ff net: can: Convert to use devm_ioremap_resource devm_ioremap_resource() is used to map raminit register. When using both interfaces the mapping for the can1 interface fails, leading to a non functional can interface.
