Hi Randy,

First bad commit (maybe != root cause):

tree: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git master
head: 1b29d271614abd97cc39782daa9d6dd70e98609f
commit: c44f15c1c09481d50fd33478ebb5b8284f8f5edb arc: iounmap() arg is volatile
date: 8 months ago
config: arc-randconfig-s051-20230618 (https://download.01.org/0day-ci/archive/20230618/202306180605.3ls3bvu7-lkp@intel.com/config)
compiler: arc-elf-gcc (GCC) 12.3.0
reproduce: (https://download.01.org/0day-ci/archive/20230618/202306180605.3ls3bvu7-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
