 type in argument 1 (different address spaces)

Hi Robin,

First bad commit (maybe != root cause):

tree:   https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git master
head:   90450a06162e6c71ab813ea22a83196fe7cff4bc
commit: f9bd34e3753ea8f1433a3ba70f03a165a1416f98 perf/arm_cspmu: Clean up ACPI dependency
date:   5 months ago
config: loongarch-randconfig-r133-20231107 (https://download.01.org/0day-ci/archive/20231109/202311090500.TY5ePlwa-lkp@intel.com/config)
compiler: loongarch64-linux-gcc (GCC) 13.2.0
reproduce: (https://download.01.org/0day-ci/archive/20231109/202311090500.TY5ePlwa-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
