Hi Felix,

I love your patch! Perhaps something to improve:

[auto build test WARNING on robh/for-next]
[also build test WARNING on clk/clk-next v5.16-rc5 next-20211217]
[cannot apply to linusw-gpio/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
