From 014bcd28a04ec085940ea3125f5ea91b16a1945d Mon Sep 17 00:00:00 2001 From: Jean Delvare Date: Wed, 12 Jan 2011 21:55:09 +0100 Subject: hwmon: (w83795) Silent false warning from gcc The code triggers a false warning with older versions of gcc: w83795.c: In function 'w83795_update_device': w83795.c:475: warning: 'lsb' may be used uninitialized in this function I admit that the code is a little tricky, but I see no way to write it differently without hurting performance. So let's just silent the warning with a needless initialization.
