Subject: [PATCH] hwmon: i5k_amb: remove redundant assignment to variable res

From: Colin Ian King <colin.king@...onical.com>

The variable res is being initialized with a value that is
never read and it is being updated later with a new value. The
initialization is redundant and can be removed.

Addresses-Coverity: ("Unused value")
