Hi Mark,

Thanks for pointing out this.

Yes, this is the duplicate-widget issue. I will fix it by moving the 
base DEC widgets out of the shared widget table and registering exactly 
one DEC widget table

per device version. Older devices use the default DEC widgets, while 
v15/Hawi selectsthe v15 DEC widgets through match data.

This avoids duplicate TX DECn MUX registration and preserves the 
v15-specific mux enum and DAPM events.

Thanks,
Prasad
