ALSA: hda - Disable sticky PCM stream assignment for AD codecs
commit 0e7adbe263f89ea2ef15b5af5e80a812b2a85025 upstream.
The sticky PCM stream assignment introduced in 2.6.36 kernel seems
causing problems on AD codecs. At some time later, the streaming no
longer works by unknown reason. A simple workaround is to disable
sticky-assignment for these codecs.
