Yes, this patch applies on next-20230213. I guess there are enough 
changes were coming from QCOM side (via Bjorn's qcom tree) as well as 
the fastrpc change (via Greg's char-misc tree).

Let me know if I should do anything once -rc1 arrives. Happy to post 
version on the -rc1 if it helps.

Thanks,
Elliot
