Hi Chun-Jie,

Thank you for the patch! Yet something to improve:

[auto build test ERROR on clk/clk-next]
[also build test ERROR on robh/for-next v5.16 next-20220110]
[cannot apply to mbgg-mediatek/for-next]
[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
https://git-scm.com/docs/git-format-patch]
