From: Guenter Roeck Date: Tue, 11 Sep 2012 20:39:08 +0000 (-0700) Subject: hwmon: (ads7871) Add 'name' sysfs attribute X-Git-Tag: v3.4.12~134 X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=17c7900f51d4cef95f95bbf3743bc9d19075052d;p=karo-tx-linux.git hwmon: (ads7871) Add 'name' sysfs attribute commit 4e21f4eaa49f78d3e977e316514c941053871c76 upstream. The 'name' sysfs attribute is mandatory for hwmon devices, but was missing in this driver.
