From aee70400184b6a8d39243b02c244aed61259a46b Mon Sep 17 00:00:00 2001 From: Clemens Ladisch Date: Wed, 11 May 2011 10:53:12 +0200 Subject: ALSA: isight: fix hang when unplugging a running device When aborting a PCM stream, the xrun is signaled only if the stream is running. When disconnecting a PCM stream, calling snd_card_disconnect() too early would change the stream into a non-running state and thus prevent the xrun from being noticed by user space. To prevent this, move the snd_card_disconnect() call after the xrun.
