SubjectRe: [PATCH v1 2/2] virtio-mmio: add features for virtio-mmio specification version 3
Hi Zha,

Thank you for the patch! Yet something to improve:

[auto build test ERROR on tip/x86/core]
[cannot apply to tip/auto-latest linux/master linus/master v5.5-rc3 next-20191219]
[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]
