From b94d3539de59ec6481e38f83c455324fd3aeabc1 Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Fri, 21 Nov 2008 09:08:06 +0100 Subject: ALSA: hda - Fix double free of jack instances The jack instances created in patch_sigmatel.c may be double-freed. The device management code checks the invalid element, and thus there is no real breakage, but it spews annoying warning messages. But, we can't simply remove the release calls of these jack instances because they have to be freed when the codec is re-configured. Now, a new flag, bus->shutdown is introduced to indicate that the bus is really being unloaded, i.e. the objects managed by the device manager will be automatically deleted. We release these objects only when this flag isn't set.
