Hi Jean-Jacques,

Thank you for the patch! Yet something to improve:

[auto build test ERROR on robh/for-next]
[also build test ERROR on geert-renesas-devel/next geert-renesas-drivers/renesas-clk linus/master v5.17-rc2 next-20220204]
[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
