Something seems fishy here. You have a ".num_sensors" for sdm8996
hardcoded to 13 but you don't have a ".num_sensors" for your new v2.
Where does num_sensors get set for everyone else? In patch #3 you
have a new "#qcom,sensors" but:
1. Nothing reads this as far as I can tell, so that means everyone
will end up with 0 sensors.
2. On your 2nd block of sensors in the sdm8996 device tree (see
earlier patch in the series) you try to set qcom,sensors to 8. ...but
since you still have a compatible of "qcom,msm8996-tsens" you'll get
13. That seems wrong. ...or did I miss something?
