3.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Guenter Roeck <li...@roeck-us.net>
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.
