This is a note to let you know that I've just added the patch titled ALSA/ASoC: hda: move/rename snd_hdac_ext_stop_streams to hdac_stream.c to the 5.10-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=summary The filename of the patch is: alsa-asoc-hda-move-rename-snd_hdac_ext_stop_streams-.patch and it can be found in the queue-5.10 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit c12315e68a81d1ddc7c80a7cc08537c3268de61e Author: Pierre-Louis Bossart <pierre-louis.bossart@xxxxxxxxxxxxxxx> Date: Thu Dec 16 17:11:27 2021 -0600 ALSA/ASoC: hda: move/rename snd_hdac_ext_stop_streams to hdac_stream.c [ Upstream commit 12054f0ce8be7d2003ec068ab27c9eb608397b98 ] snd_hdac_ext_stop_streams() has really nothing to do with the extension, it just loops over the bus streams. Move it to the hdac_stream layer and rename to remove the 'ext' prefix and add the precision that the chip will also be stopped.
