Hi Jocelyn,

First bad commit (maybe != root cause):

tree:   git://anongit.freedesktop.org/drm/drm-misc drm-misc-next
head:   7e33fc2ff6754b5ff39b11297f713cd0841d9962
commit: 3a9b77cee7502f7450c725d4ead2c4a44924d158 [4/4] drm/panic: Remove build time dependency with FRAMEBUFFER_CONSOLE
config: x86_64-allyesconfig (https://download.01.org/0day-ci/archive/20240721/202407210209.qmItlGt0-lkp@intel.com/config)
compiler: clang version 18.1.5 (https://github.com/llvm/llvm-project 617a15a9eac96088ae5e9134248d8236e34b91b1)
reproduce (this is a W=1 build): (https://download.01.org/0day-ci/archive/20240721/202407210209.qmItlGt0-lkp@intel.com/reproduce)

If you fix the issue in a separate patch/commit (i.e. not just a new version of
the same patch/commit), kindly add following tags
| Reported-by: kernel test robot <lkp@intel.com>
| Closes: https://lore.kernel.org/oe-kbuild-all/202407210209.qmItlGt0-lkp@intel.com/

Note: the drm-misc/drm-misc-next HEAD 7e33fc2ff6754b5ff39b11297f713cd0841d9962 builds fine.
      It only hurts bisectability.
