Hi Farhan,

[This is a private test report for your RFC patch.]
kernel test robot noticed the following build errors:

[auto build test ERROR on tnguy-next-queue/dev-queue]
[also build test ERROR on tnguy-net-queue/dev-queue linus/master v7.1 next-20260615]
[cannot apply to pci/next pci/for-linus]
[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]
