Hi,
Yes, I can build custom kernels and test but I won't have time for that
before the end of September so I'll do it only then.
And thanks a lot :-).

if this isn't possible, but could we maybe use the panel's OUI
Even for legacy userspace, since otherwise GETFB2 is broken and if you
switch between modifier-less and modifier-aware compositors, smooth
transitions break.
Also it's just best practice to make sure modifiers are invariant for
a given drm_fb, and that a modifier-aware kms drivers only has one
