Hi, no I haven't tried it, I can give it a try tomorrow when I
have access to my board and see whats going wrong, but I did
look at Andys for-next and the defconfig still does not have
either nvmem or qcom-qfprom drivers enabled.
Did you manually enable them? or are you seeing this with the drivers
still disabled?
