Subject: [PATCH 22/25] hda-codec: make mixemu selectable at runtime

RH-Author: Bandan Das <bsd@redhat.com>
Message-id: <1381857067-9399-3-git-send-email-bsd@redhat.com>
Patchwork-id: 54950
O-Subject: [PATCH RHEL-7 qemu-kvm v3 2/5] hda-codec: make mixemu selectable at runtime
Bugzilla: 954195
RH-Acked-by: Paolo Bonzini <pbonzini@redhat.com>
RH-Acked-by: Gerd Hoffmann <kraxel@redhat.com>
RH-Acked-by: Markus Armbruster <armbru@redhat.com>

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.
