This fix is now needed when I merge the drm tree :-(
Given that the drm tree is based on v5.8-rc2 and the commit from Linus'
tree above was merged before v5.8-rc1, the above patch should be
applied to the drm tree (and should have been part of the patch that
merged the drm-misc tree). I am a bit suprised that the drm tree
currently passes CI.
Sorry, Dave, for not cc'ing you in the original report.
