Hi,

sound/soc/soc-core.c: In function 'snd_soc_instantiate_card':
sound/soc/soc-core.c:1882: error: 'struct snd_soc_dapm_context' has no member named 'debugfs_dapm'
sound/soc/soc-core.c:1883: error: 'struct snd_soc_card' has no member named 'debugfs_card_root'
sound/soc/soc-core.c:1884: error: 'struct snd_soc_dapm_context' has no member named 'debugfs_dapm'

Looking at surrounding code it's missing ifdef for CONFIG_DEBUG_FS.
