Subject: [net-next 11/12] ixgbe: cleanup the hwmon function calls
From: Don Skidmore <donald.c.skidmore@...el.com>
When the hwmon code was initially added it was with the assumption that a
sysfs patch would be also coming soon. Since that isn't the case some
clean up needs to be done. This patch does that.
