Richard, Jingoo, would you like to take them through your > tree, or would it be easier to merge them with the ARM and SH patches ? Hi Laurent, Currently, I cannot use my git tree for backlight subsystem. Also, your patches cannot affect other backlight drivers. I think that these 7 patches would go through SH tree with my Acked-by. I will review your patches. Thank you.
