Subject: [PATCH] ALSA: hda - Fix dynamic ADC change working again
The commit eb541337b7a43822fce7d0c9d967ee149b2d9a96
ALSA: hda - Make converter setups sticky
changes the semantics of snd_hda_codec_cleanup_stream() not to clean up
the stream at that moment but delay the action. This broke the codes
expecting that the clean-up is done immediately, such as dynamic ADC
changes in some codec drivers.
This patch fixes the issue by introducing a lower helper,
__snd_hda_codec_cleanup_stream(), to allow the immediate clean up.
The original snd_hda_codec_cleanup_stream() is kept as is now.
