 RV1126B

Hi Elaine,

kernel test robot noticed the following build errors:

[auto build test ERROR on rockchip/for-next]
[also build test ERROR on clk/clk-next pza/reset/next linus/master v6.18-rc1 next-20251017]
[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
https://git-scm.com/docs/git-format-patch#_base_tree_information]
