Date: Mon, 25 May 2015 08:57:48 +0200 From: Tomas Krcka <tomas.krcka@...roup.cz> To: linux-can@...r.kernel.org Cc: andri.yngvason@...el.com, mkl@...gutronix.de, himangi774@...il.com, netdev@...r.kernel.org Subject: [PATCH] can: mcp251x: not correct register address This patch corrects addresses of acceptance filters. These registers are not in use, but values should be correct. Tested with MCP2515 and am3352 and also checked datasheets for MCP2515 and MCP2510.
