[lm-sensors] [PATCH] adm1021: individual alarm files

[Krzysztof Helt]

From: Krzysztof Helt <krzysztof.h1 at wp.pl>

This patch converts the driver to individual alarm files
as required by the new lmsensors library.

Signed-off-by: Krzysztof Helt <krzysztof.h1 at wp.pl>

This patch requires the adm1021 patch which converts
driver to use dynamic sysfs callbacks which I reposted
last week.
