Hi Maulik,

kernel test robot noticed the following build warnings:

patch subject: [PATCH v2 1/3] soc: qcom: qcom_stats: Add support to read DDR statistic
config: arc-randconfig-001-20250522 (https://download.01.org/0day-ci/archive/20250522/202505220739.yseb9RQm-lkp@intel.com/config)

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
