From bc2f6ff9239c013e9ad1ff5a64b86d85d7fc4a3f Mon Sep 17 00:00:00 2001 From: Guenter Roeck Date: Tue, 19 Jun 2012 08:00:00 -0700 Subject: hwmon: (twl4030-madc-hwmon) Initialize uninitialized structure elements commit 73d7c119255615a26070f9d6cdb722a166a29015 upstream. twl4030_madc_conversion uses do_avg and type structure elements of twl4030_madc_request. Initialize structure to avoid random operation. Fix for: Coverity CID 200794 Uninitialized scalar variable.
