I can test any tree you want me to so just tell me on which tree to apply this patch and I'll run it. In any case, it doesn't apply on v5.10 though: $ test-apply.sh /tmp/rodrigo.siqueira checking file drivers/gpu/drm/amd/display/dc/dce/dce_link_encoder.c Hunk #1 FAILED at 120 You can push a tree of yours somewhere which I can try directly, alternatively. Lemme know. Thx. -- Regards/Gruss, Boris. https://people.kernel.org/tglx/notes-about-netiquette
