support
Hi Andrei,
kernel test robot noticed the following build errors:
[auto build test ERROR on brgl/gpio/for-next]
[also build test ERROR on driver-core/driver-core-testing driver-core/driver-core-next driver-core/driver-core-linus robh/for-next linus/master v6.11 next-20240926]
[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]
