[Fix] Here is the patchset we need. https://patchwork.freedesktop.org/series/69914/ [Test] Verified on new Dell platform which use DPCD aux to adjust brightness and also others which using pwm to adjust brightness, no regression found. [Regression Potential] Low, the new DPCD method only taken effect on the platforms which are listed in the quirk.
