Subject: Re: [PATCH v2 1/3] vsscanf(): Integer overflow is a conversion
failure
Hi Demi,
kernel test robot noticed the following build errors:
[auto build test ERROR on media-tree/master]
[also build test ERROR on lee-mfd/for-mfd-next xen-tip/linux-next linus/master lee-mfd/for-mfd-fixes v6.4-rc5 next-20230609]
[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]
