Hi Andy,
kernel test robot noticed the following build errors:
[auto build test ERROR on linusw-pinctrl/devel]
[also build test ERROR on linusw-pinctrl/for-next linus/master v7.0-rc4 next-20260320]
[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]
