Subject: kernel/power/suspend.c:92:54: sparse: sparse: incorrect type in
argument 2 (different base types)
Hi Huacai,
First bad commit (maybe != root cause):
tree: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git master
head: ac865f00af293d081356bec56eea90815094a60e
commit: 366bb35a8e48198cefcd3484ac6b2374d1347873 LoongArch: Add suspend (ACPI S3) support
date: 1 year, 1 month ago
config: loongarch-randconfig-r054-20230824 (https://download.01.org/0day-ci/archive/20240104/202401041805.DwQmRjKN-lkp@intel.com/config)
compiler: loongarch64-linux-gcc (GCC) 12.3.0
reproduce: (https://download.01.org/0day-ci/archive/20240104/202401041805.DwQmRjKN-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
