Disable sticky PCM stream assignment for AD codecs
why hda_codec_cleanup_stream is called twice and this also occur with capture and playback
Isn't it just the power-save? The suspend calls hda_cleanup_all_streams().
That is, the first call is the normal one, and it doesn't clean up the stream actually because of stickiness. The second call is the real cleanup at power-saving.

by adding prinkt statement in really cleanup steam() function, really_cleanup_stream is called twice so why is second call if the stream is already really cleanup

Well, I can't reproduce it in hda-emu, so I don't know now. Try to get a stacktrace to see what's calling there actually.
