Hi Chen-Yu,

I love your patch! Yet something to improve:

[auto build test ERROR on rafael-pm/thermal]
[also build test ERROR on linus/master v6.3-rc2 next-20230316]
[If your patch is applied to the wrong git tree, kindly drop us a note.
And when submitting patch, we suggest to use '--base' as documented in
