Hi, all. I found a link error related to DRM and fbdev on branch linux-5.15.y (tag v5.15.157). It has same phenomenon with https://lore.kernel.org/all/202303150232.MBonYhiv-lkp@xxxxxxxxx/. I tried to investigate this issue and found that build will fail if CONFIG_FB=m and it will succeed if CONFIG_FB=y. [user@localhost linux]$ cat .config | grep 'CONFIG_DRM_KMS\|CONFIG_FB\b\|FBDEV_EMUL' CONFIG_DRM_KMS_HELPER=y CONFIG_DRM_FBDEV_EMULATION=y CONFIG_FB=m [user@localhost linux]$ I'm not familiar with kbuild. Can anyone troubleshoot it further? You can find .config from attachment. Thanks!
