behaviour
Hi Marcos,
kernel test robot noticed the following build errors:
[auto build test ERROR on brgl/gpio/for-next]
[also build test ERROR on lee-mfd/for-mfd-next lee-mfd/for-mfd-fixes pci/next pci/for-linus linus/master v6.17-rc2 next-20250821]
[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
