On Qualcomm SoC which has multiple Display Port controllers, using
snd_pcm_add_chmap_ctls() to add chmap controls from every ASoC hdmi codec

with same name "Playback Channel Map" already exists from the first instance.
Fix this by adding a new api wrapper to pass ASoC component name prefix to
avoid such duplicate control naming.
It implies that you have conflicting PCM objects with the same PCM
device number from the same card. How can it be?
Thanks for the inputs, this is only issue with my local changes, Sorry
for the noise, Please ignore this series.
I had some local changes to debug an issue around pcm device numbering
with backend dailinks from device tree and frontend dailinks from tplg.
Will start a new thread to discuss this issue.
thanks,
