Subject: [PATCH 05/20] hwmon/via-cputemp: Remove pointless CPU check on each CPU

From: Thomas Gleixner <tglx@...utronix.de>

The check loop for the cpu type is pointless as we already have a cpu model
match before that. The only thing which is not covered by that check would
be a smp system with two different cores. Not likely to happen.
