One question below (not tied to the change but arose due to it):

the consumer of .dspp seems to be in the RM code which is used to map the
DSPP to encoder_id but is there really any case where lm_id != dspp_id ... I
guess I am missing the context of why DSPP id needs to be tracked as LMs and
DSPPs go together. Let me also check this part internally.
For example check the SDM845, the LM_5 is tied to DSPP_3.
LM | DSPP
---------
0 | 0
1 | 1
2 | 2
5 | 3
Ah ... yes ... seems like sdm845 is the only one having this anomaly.
Thanks for clarifying.
