[PATCH 0/1] [SRU][OEM-5.10/H] UBUNTU: SAUCE: Fix backlight control on Samsung 16727 panel

[Aaron Ma]

BugLink: https://bugs.launchpad.net/bugs/1930527

[Impact]
Backlight can't be controlled on 5.11- version of kernel.

[Fix]
The panel needs DPCD to get control of backlight.
After 5.12 kernel introduced new Intel HDR backlight control, and it
works well on this panel.
Add quirk ID to enable DPCD on 5.11- kernel.

[Test]
Vendor Verified on hardware, with this quirk backlight can be changed on
5.10 and 5.11 kernel.

[Where problems could occur]
The panel backlight may not be changed.
