Subject: Re: [PATCH v3] clk: renesas: r9a09g077: Add xSPI core and module
clocks
Hi Prabhakar,
kernel test robot noticed the following build errors:
[auto build test ERROR on geert-renesas-drivers/renesas-clk]
[also build test ERROR on next-20251118]
[cannot apply to clk/clk-next linus/master v6.18-rc6]
[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
