[Qemu-devel] [PATCH 2/2] hda-codec: make mixemu selectable at runtime

From:	Bandan Das
Subject:	[Qemu-devel] [PATCH 2/2] hda-codec: make mixemu selectable at runtime
Date:	Tue, 27 Aug 2013 15:17:14 -0400

Define PARAM so that we have two versions of the "desc_codec 
and family" structs. Add a property called "mixer" whose default
value depends on whether CONFIG_MIXEMU is defined or not which
will help us call the appropriate instance init functions.
