Re: [PATCH] thermal/core: Make cooling device state change private

[kernel test robot]

Hi Daniel,

I love your patch! Yet something to improve:

[auto build test ERROR on hwmon/hwmon-next]
[also build test ERROR on linus/master v5.11-rc3 next-20210111]
[cannot apply to thermal/next]
[If your patch is applied to the wrong git tree, kindly drop us a note.
