On a S905W-based system I get the following error: debugfs: Directory 'c1105400.audio-controller' with parent 'P230-Q200' already present!
Turned out that multiple components having the same name triggers this error in soc_init_component_debugfs(). With the patch the error is gone and that's the debugfs entries.
/sys/kernel/debug/asoc/P230-Q200/aiu_acodec:c1105400.audio-controller /sys/kernel/debug/asoc/P230-Q200/aiu_hdmi:c1105400.audio-controller /sys/kernel/debug/asoc/P230-Q200/aiu_cpu:c1105400.audio-controller
Because debugfs is affected only, this may not be something for stable.
