Bug Description
Nouveau works fine with brightness controls working fine after initial boot, but I do S3 suspend, and then resume via power button, and brightness controls don't work at all, and backlight is on, but set at extremely low level.
hardware is Quadro 770M on HP 8530w laptop
/sys/.../brightness control does nothing when in this state,
suspend resume cycles after this first cycle all have the same problem.
I'll test if a full hibernate has the issue or not after this and report back.

After a suspend/resume cycle, my brightness is stuck to some low value which can't be changed with the brightness buttons or nvapoke 0x61c084 0x80000200. Both of these do work before suspend.
Output of "nvapeek 0x61c084" (both before and after suspend/resume):
0061c084: 00000401
