I've used the tree from next-20260303 instead but really the fix here is that amdgpu and other things defining a pixel_format should namespace things, I'll consider if a revert is more sensible. --vafmZqH34VLuiaf8 Content-Type: application/pgp-signature; name="signature.asc" -----BEGIN PGP SIGNATURE----- iQEzBAABCgAdFiEEreZoqmdXGLWf4p/qJNaLcl1Uh9AFAmmoQT4ACgkQJNaLcl1U h9BXbwf+NMgzm+EwZ+oRef+uo7RxieWsON/heDAaLQf7kj0S1+EUF48sTw++m2Xp iS4EtFT0QNZCVTgH5JbbpxFkv7J9Z+Cycf9M6l9aZTsof8zzGWE1aYvrxXOo3Fw0 0ZXJlPOrxwmJldcQsf3F+rZEVY74BCL24XbQD5qHje5nqKKmlGA+XkjaZXW9KqHL /icsEcg+PbZR226vH2nrrTcAUj6nX3WVcZw294QDas+N1Un/P7vDr2HOqxAiBzvO 9bzg8mUBf2fcCFQl+rNP88wa6ODwqeN0/w9twk33EVXqcJR86FfMZRvrrdcEc1gZ Q4CM6t//I3zUfNNsrbV5tb/x3uu4zg== =c3Fj -----END PGP SIGNATURE----- --vafmZqH34VLuiaf8--
