Hi Dave and Daniel,

Here goes drm-intel-fixes-2021-12-02:

- Fixing a regression where the backlight brightness control stopped working.

- Fix the Intel HDR backlight support detection.

- Reverting a w/a to fix a gpu Hang in TGL. The w/a itself was also
for a hang, but in a much rarer scenario. The proper solution need
to be done with help from user space and it will be addressed later.

Thanks,
Rodrigo.
