Got Aava Inari 8 (8086:0f31 too) with backlight level fixed at boot (and a
weird "milk flooding" when DPMS kicks in...) -- should it be safe to try your
patch given the same SoC but quite different panel and probably firmware
(64-bit one)?

The magic constants in both
https://github.com/jonpry/t100_patches/blob/master/3.17.patch
and
https://github.com/AdamWill/baytrail-m/blob/master/kernel/baytrail-backlight.patch
look the same at least and the panel specific delay handling seems to have been
dropped in the latter but that's about as much as I can read in interdiff.
