Thanks, but actually there was already a fix. Take a look at linux.git/master: commit 927011b65a875302d08709bbe82eaf4d0d96c5d5 Author: Yury Norov <[email protected]> Date: Mon Apr 27 22:49:41 2026 -0400 drm/amdgpu: fix build for CONFIG_DRM_FBDEV_EMULATION=n I encountered this in net-next, but the above has yet to be put into net-next.
