alsa-project/alsa-lib pull request #79 was opened from jason77-wang: We plan to use the sound driver module's name for the top ucm's name, I checked it on 3 different ASoC machines, the device/driver links to machine driver while deice/driver/module links to the sound driver module, so change the code to readlink the device/driver/module first, if it fails then readlink the device/driver. This is the output from those 3 machines: $readlink /sys/class/sound/card0/device/driver ../../../../bus/platform/drivers/skl_hda_dsp_generic $readlink /sys/class/sound/card0/device/driver/module ../../../../module/snd_soc_skl_hda_dsp $readlink /sys/class/sound/card2/device/driver ../../../../../bus/platform/drivers/acp_pdm_mach $readlink /sys/class/sound/card2/device/driver/module ../../../../module/snd_acp3x_rn $readlink /sys/class/sound/card0/device/driver ../../../../bus/platform/drivers/sof_sdw $readlink /sys/class/sound/card0/device/driver/module ../../../../module/snd_soc_sof_sdw Signed-off-by: Hui Wang <hui.wang@xxxxxxxxxxxxx> Request URL : https://github.com/alsa-project/alsa-lib/pull/79 Patch URL : https://github.com/alsa-project/alsa-lib/pull/79.patch Repository URL: https://github.com/alsa-project/alsa-lib
