[Impact]
[Fix]
[Test]
[Where problems could occur] |
[Impact]
The brightness could not be adjusted, and after resumed the screen is blank.
[Fix]
It looks like below commit in oem-5.10 introduces the regression
ade9f1d9f14ef drm/i915/dp: Program source OUI on eDP panels
But it's not a culprit as mainline kernel doesn't have this issue.
We add a quirk on this commit to make it only affect on a certain Dell platform to avoid the issue. Will figure out the problem and submit a formal fix later.
[Test]
Verified on Dell and HP platforms, both platforms work well.
[Where problems could occur]
The quirk should be pretty safe for other platforms. |
