From 33cf75656923ff11d67a937a4f8e9344f58cea77 Mon Sep 17 00:00:00 2001 From: George Cherian Date: Fri, 25 Jul 2014 11:49:41 +0530 Subject: [PATCH] can: c_can_platform: Fix raminit, use devm_ioremap() instead of devm_ioremap_resource() 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.
