Linus' tree feeds to drm-tip via drm-intel-fixes, but I guess we haven't done backmerges from Linux' tree to drm-next to drm-intel-gt-next with that commit. Once you applied the patch, dim rebuilt drm-tip, which now got the same change from both drm-intel-fixes and drm-intel-gt-next. It happens. But in general, if there are regressions with blank screens at boot occurring in Linus' tree, the fix needs to move much faster.
