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.
Hi Heiner,
Thanks for the patches!
This one has been bugging me for quite some time, I'm glad you took time to fix it.
I'm sure Martin and the BayLibre folks will soon review both of your patches, just wanted to thank you.
/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.
