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. Signed-off-by: Jean Delvare <khali@linux-fr.org> Acked-by: Guenter Roeck <guenter.roeck@ericsson.com>
