** Description changed: [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.
