Yah, installed that and was able to repro:

arch/x86/kernel/cpu/cacheinfo.c:880:24: warning: Value stored to 'this_cpu_ci' during its initialization is never read [clang-analyzer-deadcode.DeadStores]
        struct cpu_cacheinfo *this_cpu_ci = get_cpu_cacheinfo(cpu);
arch/x86/kernel/cpu/cacheinfo.c:880:24: note: Value stored to 'this_cpu_ci' during its initialization is never read

Thx.
