[alsa-devel] [PATCH 2/7] ASoC: topology: Remove widgets from dobj list

[Pierre-Louis Bossart]

From: Amadeusz Sławiński <amadeuszx.slawinski at intel.com>

Currently when we unload and reload machine driver few times we end with
corrupted list and try to cleanup no longer existing objects. Fix this
by removing dobj from the list.
