The commit c560a6797e3b ("ALSA: core: Remove child proc file elements recursively") introduced a regression that ELD/codec information files can not be found on /proc/asound/cardX/. This patch corrects it.
Signed-off-by: Lu, Han han.lu@intel.com
This doesn't fix correctly since snd_card_proc_new() isn't the place to create the real proc file entry. It should be created at the device registration time.
I'm going to post the fix patch series.
thanks,
