[PATCH] acer-wmi: Using zero as the first WMI instance number

From: Lee, Chun-Yi
Date: Tue Jun 20 2017 - 05:06:45 EST


Pali RohÃr found that there have some wmi query/evaluation
code that they used 'one' as the first WMI instance number.
But the number is indexed from zero that it's must less than
the instance_count in _WDG.

This patch changes those instance number from one to zero.
