Message-Id: <2e0cc42eaefa3fa3adf072130706f15e6b546638.1402303820.git.jslaby@suse.cz> Date: Mon, 9 Jun 2014 10:49:30 +0200 From: Jiri Slaby <jslaby@...e.cz> To: stable@...r.kernel.org Cc: linux-kernel@...r.kernel.org, Josef Gajdusek <atx@....name>, Guenter Roeck <linux@...ck-us.net>, Jiri Slaby <jslaby@...e.cz> Subject: [PATCH 3.12 035/146] hwmon: (emc1403) Support full range of known chip revision numbers From: Josef Gajdusek <atx@....name> 3.12-stable review patch. If anyone has any objections, please let me know. =============== commit 3a18e1398fc2dc9c32bbdc50664da3a77959a8d1 upstream. The datasheet for EMC1413/EMC1414, which is fully compatible to EMC1403/1404 and uses the same chip identification, references revision numbers 0x01, 0x03, and 0x04. Accept the full range of revision numbers from 0x01 to 0x04 to make sure none are missed.
