[cannot apply to swiotlb/linux-next]
[if your patch is applied to the wrong git tree, please drop us a note to help

base:   https://git.kernel.org/pub/scm/linux/kernel/git/mst/vhost.git linux-next

        make C=1 CF='-fdiagnostic-prefix -D__CHECK_ENDIAN__'

If you fix the issue, kindly add following tag as appropriate
Reported-by: kbuild test robot <lkp@xxxxxxxxx>


sparse warnings: (new ones prefixed by >>)

>> drivers/virtio/virtio_bounce.c:22:21: sparse: sparse: symbol 'virtio_pool' was not declared. Should it be static?
>> drivers/virtio/virtio_bounce.c:79:8: sparse: sparse: symbol 'virtio_max_mapping_size' was not declared. Should it be static?

Please review and possibly fold the followup patch.
