[alsa-devel] [PATCH v2 14/25] ASoC: soc-core: define soc_dpcm_debugfs_add() for non CONFIG_DEBUG_FS

[Kuninori Morimoto]

From: Kuninori Morimoto <kuninori.morimoto.gx at renesas.com>

soc_dpcm_debugfs_add() is implemented at soc-pcm.c under CONFIG_DEBUG_FS.
Thus, soc-core.c which is only user of it need to use CONFIG_DEBUG_FS, too.

This patch defines soc_dpcm_debugfs_add() for non CONFIG_DEBUG_FS case.
Then, we can remove #ifdef CONFIG_DEBUG_FS from soc-core.c
