Since the gamma_set_common() function for previous SoC,
such as mt8173 and mt8183, is designed for 9bit-to-10bit
conversion.
mt8195 is using 10bit-to-12bit conversion, which is
not compatible with the previous function.
Thus, need to update the function to fit the need of mt8195.
Hello,
can you please respin and fix this series on the latest linux-next?
Besides, please test it carefully: as far as I can see, GNOME Night Light
(or others) are not working on MT8195 (color temperature/ccorr).
As for gamma itself, that's not working either; you can test it with a tool
that will create a color profile by applying a new VCGT table, please look
at [1] if you need tools.
We can confirm that color correction works on at least MT8192 (colord), so
it's MT8195 at fault.

Nevermind. I've actually fixed this code and refactored it a bit as well.
I'll push my own version soon. No action required.
Regards,
Angelo
