Hi Thorsten,

First bad commit (maybe != root cause):

tree:   https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git master
head:   8c06da67d0bd3139a97f301b4aa9c482b9d4f29e
commit: 5eefb477d21a26183bc3499aeefa991198315a2d net: smc91x: Fix m68k kernel compilation for ColdFire CPU
date:   2 days ago
config: m68k-randconfig-r123-20240516 (https://download.01.org/0day-ci/archive/20240516/202405160853.3qyaSj8w-lkp@intel.com/config)
compiler: m68k-linux-gcc (GCC) 13.2.0
reproduce: (https://download.01.org/0day-ci/archive/20240516/202405160853.3qyaSj8w-lkp@intel.com/reproduce)

the same patch/commit), kindly add following tags
