Subject: [PATCH 2/2 v2] regulator: max8952 - fix max8952_set_voltage
Date: Tue, 26 Oct 2010 07:55:54 +0800 [thread overview]
Message-ID: <1288050954.2323.3.camel@phoenix> (raw)
In current implementation, vid is declared as u8,
then "vid == -1" is always false, and "vid >= 0" is always true.
Thus change it to s8.
