Hi David,
Thank you for the patch! Yet something to improve:
[auto build test ERROR on clk/clk-next]
[also build test ERROR on linus/master v6.3-rc3 next-20230322]
[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
