From 0b7a2e9cefd7614e68520127751f76583498df6c Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Tue, 14 Aug 2007 15:18:26 +0200 Subject: [PATCH] [ALSA] hda-intel - Don't do suspend if already powered down In the power-saving mode, the suspend is done dynamically at power-down. So we don't have to call suspend stuff explicitly if it's already powered down.
