From 2ccc99b7b71976d15822ae7c41cd2ccda66d5076 Mon Sep 17 00:00:00 2001 From: Stephen Hemminger Date: Tue, 13 Jun 2006 17:17:27 +0900 Subject: [PATCH] sky2: set_power_state should be void The set power state function is cleaner if it doesn't return anything. The only caller that could fail is in suspend() and it can check the argument there.
