From 44728e97c35ef31d649dafbbada665e37176f5da Mon Sep 17 00:00:00 2001 From: Daniel J Blueman Date: Tue, 18 Dec 2012 23:59:33 +0800 Subject: [PATCH] ALSA: HDA: Fix sound resume hang Resuming a switcheroo'd HDA controller hangs since the completion is one-shot (thus works the first time). Fix by using completions that explictly need rearming, so remain fired before.
