I got the patch working in 4.9.6. But in 4.17.3 the backlight controls no longer work after suspend.
Wierdly though, the "nvapeek" output is the same after suspend as before: # nvapeek 0xe100; nvapeek 0xe28c; nvapeek 0xe104 8; nvapeek 0xe280 8 0000e100: 001c1100 0000e28c: 00000180 0000e104: 72266640 0441474b 0000e280: 24444747 00000000 ...suspend... # nvapeek 0xe100; nvapeek 0xe28c; nvapeek 0xe104 8; nvapeek 0xe280 8 0000e100: 001c1100 0000e28c: 00000180 0000e104: 72266240 0441474b 0000e280: 24444747 00000000 Something else has changed.
