While boot testing arm x15 devices the Kernel warning noticed with linux next tag 20200825.

But considering that multiple things related to OPP broke recently, it may be a OPP core bug as well. Not sure though. Can you give me delta between both the next branches for drivers/opp/ path ? I didn't get these tags after fetching linux-next.
