Hi Tomer,

kernel test robot noticed the following build errors:

[auto build test ERROR on clk/clk-next]
[also build test ERROR on pza/reset/next linus/master v6.9-rc7 next-20240510]
[cannot apply to pza/imx-drm/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
