[alsa-devel] [PATCH v3 12/21] media: au0828 fix au0828_create_media_graph() entity checks

[Shuah Khan]

au0828_create_media_graph() checks if entity.links is null
or not to determine, if vbi_dev and vdev entities have been
registered. Checking entity.parent field is right way, as
parent field gets initialized when entity is registered. Fix
it to check entity.parent field.
