Re: [PATCH 3/3] iommu: Enable compile testing for some of drivers
by kbuild test robot
Hi Krzysztof,
I love your patch! Perhaps something to improve:
[auto build test WARNING on iommu/next]
[also build test WARNING on v5.5-rc4]
[if your patch is applied to the wrong git tree, please drop us a note to help
improve the system. BTW, we also suggest to use '--base' option to specify the
base tree in git format-patch, please see https://stackoverflow.com/a/37406982]
