Hi Arnd,
First bad commit (maybe != root cause):
tree: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git master head: 1ef6663a587ba3e57dc5065a477db1c64481eedd commit: 09f6b27d5ddd9ad0ec096d1b0f8decdacc70f0f8 ARM: dove: multiplatform support date: 1 year, 3 months ago config: arm-randconfig-r071-20230627 (https://download.01.org/0day-ci/archive/20230627/202306271413.5vS46KMc-lkp@intel.com/config) compiler: arm-linux-gnueabi-gcc (GCC) 12.3.0 reproduce: (https://download.01.org/0day-ci/archive/20230627/202306271413.5vS46KMc-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/202306271413.5vS46KMc-lkp@intel.com/
