This comes from tools/power/cpupower/utils/idle_monitor/hsw_ext_idle.c by the way and can be reproduced by make -j$(nproc) -C tools/power/cpupower CC=clang all.

@tpgxyz In the future, would you like an explicit Reported-by: tag in the commit message? I will always include a link to the original issue so you get credit that way but I am happy to add it to the commit message as well. If so, let me know what email you would like it under.

I probably should have marked it as cc stable but Sasha's AUTOSEL process has been picking up most of my warning fixes so I expect this to be no different.
