From 5f4513864304672e6ea9eac60583eeac32e679f2 Mon Sep 17 00:00:00 2001

Subject: hwmon: (applesmc) Check key count before proceeding
After reports from Chris and Josh Boyer of a rare crash in applesmc,
Guenter pointed at the initialization problem fixed below. The patch
has not been verified to fix the crash, but should be applied
regardless.
