Hi Artur,
First bad commit (maybe != root cause):
tree: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git master
head: 2a163a4cea153348172e260a0c5b5569103a66a3
commit: 1e21acb7fbfb15fcb4afe21fb5a50a1bc00743ec sh: hd64461: Make setup_hd64461() static
date: 8 months ago
config: sh-randconfig-r133-20241123 (https://download.01.org/0day-ci/archive/20241123/202411231306.6FROo9Kg-lkp@intel.com/config)
compiler: sh4-linux-gcc (GCC) 14.2.0
reproduce: (https://download.01.org/0day-ci/archive/20241123/202411231306.6FROo9Kg-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
