Hi,
it looks as if 'reconfig' feature is broken since the sysfs attributes have been moved to device attributes. In hda_sysfs.c:reconfig_codec() the device is cleared with snd_hda_codec_reset() which calls snd_hdac_device_unregister() which removes the sysfs entries (including the currently in-use 'reconfig'), the re-registration fails afterwards in snd_hda_codec_build_controls(). I am not sure when things got broken, but snd_hda_codec_reset() called from reconfig_codec() unregisters the device and removes the sysfs entries where in the past it only stripped all configurations (pcms, controls ...) from the device.
Regards, Jochen
