 approximation

Hi Frank,

kernel test robot noticed the following build errors:

[auto build test ERROR on v6.4-rc6]
[also build test ERROR on linus/master]
[cannot apply to clk/clk-next next-20230613]
[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#_base_tree_information]
