I know you're working on this already so just for completeness:
We discussed in the chat that there should be no s4 here at all since
sensor hwid=4 is not used on MSM8939. I think all the definitions are
already correct so you just need to rename s4 -> s5, s5 -> s6, s6 -> s7,
s8 -> s9.

Since it looks like another version is needed to fix the tsens problem,
I'd appreciate if you squash in the following diffs for consistency with
my WCNSS compatible change for 8916: Could also send it as follow-up
later though.
Thanks,
Stephan
