From b0db6063dba4ee02dfda7411ec3aaf8f0fbda0f7 Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Wed, 21 Nov 2012 08:35:42 +0100 Subject: [PATCH] ALSA: usb-audio: process pending stop at PCM hw_free and close PCM hw_free and close should wait until all the pending stop operations have been finished. Basically only PCM trigger callback should use non-wait calls.
