SubjectRe: [PATCH 2.6] hwmon: via686a: save 0.5k by long v[256] -> s16 v[256]
Hi Greg,

> Unfortunatly, no one noticed that this patch adds a build warning :(

I'm sorry about that, I though I had checked but now it seems not. A new
patch addressing the issue follows.

Thanks.

----------------------

We can save 0.5kB of data in the via686a driver.
